The photos below show Boom Tubes for the S4RS but are made of pre-production materials, without exhaust tips just yet, and when they are completed will be available in natural stainless or ceramic black finishes.  They completely replace the stock header/udder and make provision for the O2 sensor.  Baffles are specially designed to mate with the Boom Tubes but I'm told they're still loud.  Just how loud?  It's going to be a long 6 weeks or so.  I think Mark has done an excellent job (again).  Check out the increased ground clearance.

Looks nice!  What kind of tips and can you post a vid w/ sound?
 [moto]

Dude that looks awesome  :) I can't wait to see the finished produt....

Maybe i can convince him to build a prototype for my bike?

Lookin good.

Be nice if someone figured this underbike exhaust thing out for us S*R owners.  I've seen options but they all are for DSS bikes.

Quat-D ExBox?

exbox is ugly and sounds tinny. i want these boomtubes on my S2R bad. REAL bad.

Does anyone know if this is the exact format they will be making, I know they are switching over to having them manufactured instead of hand made but if this exactly what they will be comming out with this year (???)

Have you called Motocreations and talked about making you a set?  I believe NAKID has boomtubes on his S2R 1000.

CRex, what kind of finish are you planning for you boomtubes?  Ceramic?

Right on,,, [thumbsup]. What is the OD of the pipe. Do we use any part of the OEM exhaust?

christ, that thing probably sounds ANGRY.....

and everyone says my Rs with termi's is loud  8)

+1.  no offense to others but I'm not a fan of the box on the exbox.  there are some sweet underbike exhausts out there for the monster (that include a crossover, baffles, etc); just not any I've seen other than these for the SSS monsters. 

This one I can answer... yes- black! 

Yup!

{note: hopefully this doesn't sound too commerical -- it isn't meant to be}

I'm still surprised by the response of BoomTubes by enthusiasts. Originally they were created for my DesmoDevil bike to retain cornering clearances and to visually keep the rear tire open as I'd have hated to hide it.  Thanks to enthusiasts, I've now handmade dozens over the past four years for friends or customer bikes.  Mostly all have been a variation of the original straightpipe iteration with baffles (aftermarket or of my own design). Unfortunately I haven't had the time with everything else happening at MotoCreations (DesmoDevil deliveries in particular) to produce more or jig for manufacturing production.  Until now that is.

With the move to outside of Tacoma, WA -- I've finally had the time to move a LARGE number of parts I've designed / prototyped and tested the past few years.  BoomTubes being the first most will see. (unless you see someone doing durability testing of other upcoming parts)  The past few months, I've played with the BoomTubes design, routing, sound and visual characteristics.  Then some simulation modeling outsourced to study exhaust flows.  They are no longer just "straight pipes" as what I've done in the past. (Wait until you see the final product)  All systems will be CNC mandrel bent in stainless and CNC welded. (I hate ugly welds!)  It took three months to find the facility that would actually produce what I want to the quality control standards I absolutely require.  Currently they have the S4R, S4Rs and S4 systems for the 4-valvers and are CMM'ing, building jigs and over the next few weeks will get me back the pre-production iteration for final testing/fitment.  Then production starts for customer delivery first against the database with people who've been inquiring for months. Then they will be released to the general public.

Iterations to follow within 60-90 days after the above ship are for the 695, 620, 800, 900, HyperMotard, S2R800 and S2R1000 -- and the 696.

All bikes are dyno'd with factory system (or if already using existing aftermarket system).  System built and optimized.  Then dyno'd again.  Fuel maps as required will be done and provided also via download for "standardized" scenarios.  Will do different mapping for the different baffle scenarios available.

The interesting part of this for myself is the move from "handmade" to "manufacturing production" and retaining "quality control".  I think I've spent more time the past few months doing engineering, stuck in meetings, conference calls, visiting facilities, checking references, building e-commerce capabilities, merchant services setup, business re-org or dyno testing than in fabrication itself. (It almost reminds me of my dot.com Internet days!) Fortunately I have four years of design and prototype experience to build exactly what I want now and how I want it to sound and function.

Thanks for the responses everyone!  Admittedly this is an exciting time upcoming here at MotoCreations -- and hopefully by this Fall we will be known for more than just our wild DesmoDevil line of motorcycles (and customer Monster projects) we have built over the past few years.

That is awesome... You can expect a customer as soon as you start making ones for the 695!

Congrats on the good work and excelent quality!

Also wanted to say thanks to "c-rex" for allowing use of the S4Rs for prototyping of parts while he was recovering from wrist surgery!  [thumbsup]

I never had looked all that closely at the S4Rs as I personally am not a fan of the 4-valver in the Monster frame. (Black Fog being the exception but heavily modified)  I've ridden enough S4's, S4R's, etc -- my opinion was reinforced.  I do though have to say that the S4Rs as per c_rex's is a fabulous bike -- that is one fabulous engine! (and suspension and brakes) Although I won't buy one for myself given what I build myself, I will find an engine / wiring and suspension / brakes and use that as a basis for an upcoming MotoCreations bike.  It really was that impressive of a bike given those components about a normal Monster.

So if someone asked my verdict today in regard to the S2R1000 -or- S4Rs?  I'd highly recommend the S4Rs now.

Mark you mentioned "Black Fog" I love that  bike and it is a huge inspiration. Will the production boomtubes be available in that exact look (the pictured prototype look angled more back) maybe i am mistaken but the set on "Black Fog" seem to come out more straight? I have an s2r 800 and can't wait to get my hands on a set. Is there any sound clip that you have i know there is a youtube video but any additional clips?

Actually the system on Black Fog is a one-off due to the swingarm setup. (note how exhaust comes out and winds back around and under swingarm and then enters outlets)  It is composed actually of 90% factory exhaust tubing from a new 996 and 996R take-off systems that were heavily heavily modified -- nothing is even remotely stock. (Tig welded and then welds polished out)  Thus Mike then has all the factory Ducati part #'s throughout the system.  I thought it would be fun and add to the "factory prototype look" of the bike we were going after.  Interestingly I've seen people write the exhaust part #'s down thinking they could go to a dealership and purchase such a system.  Hopefully nobody has tried actually ordering one from a dealer!  (note: I've had someone call with the part #'s and try to order it from myself already)

BoomTubes will be angled back 15 degrees for production systems -- @85% of everyone prefers this look.  Some of the negatives of the original BoomTube "direct out" system are: your foot gets warm when you put it down at stoplights; whomever is directly to the right of you will HATE you; reverb from walls/underpasses is a bit disconcerting for some folks.  Pros: More minimal looking; you can "blast" drivers with windows open or pedestrians while at a stop.  Angled exhausts have none of the negatives and still retain most of the fun ones too. 

Biggest perk is disctinctive looks (especially if SSS configuration), unique sound and LIGHT WEIGHT.  I'm waiting production weight figures -- but the BoomTubes on my prototype DesmoDevil only weigh 7.2lbs with baffles. (I think Nakid's system was @9.5lbs -vs- 28+ stock)  Also mass is under the engine instead of hanging out the sides or above the polar moment of the bike. (the first few miles riding them is strange as it changes the weight distribution of your Ducati a bit given the reduced rear mass)

My next bike will probably be an upgrade from my S2R 800 to a 1k. I need to get myself on your list of future customers [thumbsup]
Do you know what will be needed in the ECU/PC/map/??/?? department. I would like an open air box and no hassles - plug and play - no new ECU, no PC, no closed loop games, maybe even no need for adjusting the A/F ratio - low fuel consumption - great sound with the CF bass - .......

I'm probably asking too much, but what can I expect?

+1.  Stylistically speaking I hope the final version of the boom tubes curve upwards a tad as opposed to just sticking straight out (horizontally). Either way they are sick!

That's how I asked him to do mine...

enjoyable scenario...

a-hole pulls up next to you at a light blasting his rick astley, looks at my bike and makes a disapproving face.

i tilt the bike to the left and give it some gas.

a-holes hair stands up as the exhaust blasts him in the face, followed by the rapid rasing of his window, and the mouthing of curses.

equally entertaining is a person yapping away on their cell phone getting the same treatment...

Mark did the pipes on the SS2R too BTW...  I love 'em!  Best part?!?  My customer loves them too.



Police?!?  [leo] not so much.

Since we're making this a BoomTubes lovefest...

(http://i249.photobucket.com/albums/gg216/mikesixtysix/blackfog/IMG_3645.jpg)

I love the look and you can put me down for a set as well!  The sound worries me though, been pulled over twice for noise and I already set off everybody's car alarm's on my street.  

Normally I don't care but if I get off at midnight or later....

Pfff. Noise violations and speeding tickets are part of the hooligan life style my friend. ;D

I have to admit it but I've goosed the throttle a few times when someone is sitting next to me at a light talking on the phone.   ;D

I can't imagine having a beautiful rear wheel with a singlesided swingarm setup and then hiding it all behind an ugly exhaust!  Glad to hear your customer was happy.

The craziest set of BoomTubes ever?  On Ricky's MotoCreations HyperDevil Ducati (996-style bodywork on DesmoDevil chassis) which as of this weekend is in final primer awaiting paint.  Debut this summer. (He is on the board here but just waiting until finished) The exhaust are 4-port.  Only set that will ever get built with all the twists and turns to make happen. Definitely matches the style of the bike!

(http://motocreations.com/dmf/Ricky4port.jpg)

I have been waiting for these for a long time....... my s4rt is begging for a set of pipes. I can't wait to see the finisshed product.  And once again  c-rex hats off to you for an outstanding work of art.

aw shucks- the bikes in this community are responsible for 90% of the way my bike looks.  Just look up at Magnus' "Black Fog"!~

Magnus' blackfog has the SEXIEST set of boom tubes. If i can get those, holy cow batman! I dont like the ones that point of at an angle. So how much do i have to pony for a set of boom tubes like Magnus' I WANT!!!!!!!!

and i look right back at yours c_rex...  your s4rs is sinister!

Hey NAKID did you run into the surging problem with the tubes or did you unplug the o2? I had done my own exhaust and it is bassically straight pipes not much for baffles and since then mine surges when cold.  Was told that I didn't have enough back pressure to heat up my o2 sensor so it couldn't function properly so I unplugged it and my engine light came on.

I have an 06 so no engine light problems. I had my O2 sensor unplugged before the boomtubes. I have an early set so there are no provisions to hook up the O2. I don't currently have any surging. "Occasionally" i get a bouncing idle when the bike is cold, but not too often...

A note for the S4R enthusiasts.  Just dyno'd a S4R with BoomTubes.  One more horsepower than the Zard exhaust that was on the bike previous. (same dyno although warmer temps today) Also no peaks/drops as per the Zard system - it's a real nice curve that surprised me. I'll post the dyno runs in a few weeks when available for sale.  I'm curious to see what the final horsepower levels are once the manufactured system ships on the S4Rs Monster! (in comparison to the stock udder setup)

Everyone keeps telling me that BoomTubes will only LOSE horsepower and torque -- especially in comparison to stock or aftermarket exhausts.  I think I'm going to have a few surprises (besides the weight differences) for everyone given the back-to-back dyno runs we've been making as of late in testing and system optimization.

That is interesting. Just the fact that U never lost any HP is inspiring.

What ECU or other tuneing device does this bike have ?

I would like to see what the RWHP is.

So these open tubes bring more hp&torque?! I'm really curious to see a dyno run...anyway I don't want to see too many runs on same bike with factory ecu, because that bike will need some engine work.

I dont think these are straight pipes are they? i would like them baffeled to a certain extent. As cool as straight pipes are, my hearing has went to shit since i got my S2R1k. (open udder)

Answers: PCIII, crossover (although they look the same as straight), baffled.

As soon as you plan on prototyping for 695 give me a shout  [thumbsup]

Waiting on dyno runs and a vid w/sound.  Are you re-using the stock headers on the rs bikes? 
Any more pics from the other side, under, etc?

I've got an 07 S4R with a full termi kit (dp ecu as well).  Would you expect a drop in performance if i went with the boom tubes exhaust under this setup?  And also, what is the I.D. of the boomtubes?  (I like the look of a 50mm pipe on my bike.)

Any updates on the dyno runs?  What about the other questions?  [drink]

For the S4Rs we need to overcome one unique obstacle in regard to the system.  Thus special tooling is being made by a 3rd party (thus the delay) due to the oblong exhaust port unique to the S4Rs that immediately is radiused and changed in outer profile into round tubing and then offset for the vertical cylinder for suspension linkage clearance.  Front exhaust port routing isn't as horrible as you have a few inches to make everything work.  Worse case scenario is we will have to do the exhaust headers for the S4Rs by hand fabrication. (and raise the MSRP for S4Rs systems to account for that)

Once I have a production setup here, there are a couple of local S4Rs that will get dyno'd with BoomTubes (w/Rapidbike setup via Anthony / DesmoWorks with mapping here).  All are active posters here on the DMF and I'm sure they will post.  I'll take orders as mentioned previously against the existing database first.  Options will be baffle variation and exhaust tips themselves (there are a few options in the works).  Exhausts will be stainless or black coated.

For those at MotoGP this year, a Ducati Monster enthusiast from Mt. Shasta will have his red S4R bike with pre-production BoomTubes on it at Ducati Island.  (I'm hoping to route him a production set if available  -- exhaust 2-into-1 headers appear to be no problem) His first ride was 2+ hours and many more since in the NorCal area.  Given his profession, they are good around town -- provided one keeps it under 6000 rpm.  When out in the country, he opens it up as they literally sing for miles.  He seems much happier now than with the Zard's that were on it previous.  (and I'm getting a lot of inquires from everyone who has seen/heard his S4R in the area)

(http://www.motocreations.com/dmf/mtshasta.jpg)

Damn, wish they'd work for the 04-06 S*Rs.  That's exactly what i want on my S2R.  I'm talking to a number of shops about custom builds but haven't found one i'm comfortable with yet.

What would vary on a 2005/2006 S4R/S2R version of these?   To get this to work would it just be a matter of the header or is there some kind of routing difference as well?

Mark told me mid August to prototype the S2R 800. Not sure if I can wait that long.

I can't wait. Its funny how all the SSS nuts are swarming this thread, the SSS is basically why I went with the s2r over the 695. Like he said, why cover that up with pipes, stock or otherwise.

I think the main difference in the S4RS an the other SSS bikes is the diameter of the header tube. the S4Rs is suppose to be larger, and i think theres also a difference in the location of where the headers connect to the heads because the S4R and S2R1000 have different strokes.

If you look at the custom SBK Swingarm black foggy, that set of boom tubes was completely welded together by stock pipes, so thats a possibility if you know how to weld/ know someone who does.

i have an 800 S2R so the S4R parts are the same as mine (midpipe, exhaust, etc).  I'm more concerned about the elliptical shape motocreations mentioned.  if that's true then I'd need to replace the entire header or atleast cut and weld the correct size shape header onto that part which could lead to other issues.  I'm also concerned about routing since the engines are different layouts.

Yea i think the S4R share the same parts, but I remember reading the Rs has larger headers. Why the elliptical shape issue? excuse me, but I can't seem to find Motocreations post on that issue (ctrl F:ELLIPTICAL  :P)

oblong -- elliptical.  maybe I misunderstood but it sounds quite different regardless.

There are three different styles of exhaust ports.

#1)  old-style 4-valver: 748/916/S4/S4R -- two round exhaust ports coming out of the head.  Exhaust header is a 2-into-1 to recombine the exhaust ports.

#2)  S4Rs: One giant oblong port -- this needs to transition to round for the exhaust system routing itself. Here is a pic of the gasket for the exhaust port:
            (http://motocreations.com/dmf/S4Rs_gasket.jpg)

#3) 2-V'ers.  One round exhaust port (although there are small differences in early 2V's -vs- DualSpark series).

The exhaust port on the S4RS is more centered on the engine due to the new different head design.  Thus the clearance issue with the rear suspension linkage. (And why Ducati made the change in rear suspension for the new Monsters for use later with the newer Testastretta heads)

So what is the difference between the S2R 1000 and S2R 800?

Yikes, even higher pricing?  I'm lazy, and thats why I wanted to buy a set, but $750+ for 8 some odd feet of stainless tube and a pair of flanges is to much for me.  Time to build my own :)

Round tube to oval hole....Mandrel die, pressed, done.

Do you have access to a Mandrel bender? You could custom bend your own pipes easily if you did. But more often than not, you don't see high quality pipes that are bent numerous times because it is impossible unless they are very generous bends. That's where wielding comes in handy, but to weld SS, you need a skilled TIG guy, not just some random dude on the corner of the st.

But if you DO have all that. Damn hell! Go for it! Nothing beats homemade customs parts!! Now Im getting desprete enough to just get some left over pipes and go do this myself. It wont look too nice though since it would just be scrap exahust pipes from other ducatis.

I think it's just the length of the pipes needed for the extra stroke...

That makese sense, but the Quad D exbox works for both S2R800 and S2R1000. The only difference in the newer models is the O2 sensor port. So who knows. ???

Are you sure they aren't seperate models?

Yes, there was a member who had both an S2R 1k and S2R800 and they were interchangable, minus the port for the O2 sensor since he actally had one that was sold for an S2R 800. he contacted motowheels or quad d themselves at one point since an S2R1k buyer wanted it, and it turns out it does fit. I looked up the bore x stroke of both bikes and the stroke is different on each, so i dont know what to say lol. unless someone who has worked on both bikes steps up.


Whats the update on the tubes? im stil waiting on you guys to make an S2R1k version after you release the S4Rs one!

I have an S2R 800 (2006), I bought a Quat D Midpipe, and it came with an extra section of stainless tube to hook up to the Vertical Cylinder on the S2R1000.  Not sure if that bit of info is worth anything to anyone or not...But there it is..LOL

You'd have to talk to Mark, I'm just the guy lucky enough to have the prototype on my bike...

Thats what I did in my previous career, TIG weld cages, chassis work, exhaust, headers, turbo manifold, collectors...etc...

Never got really good with Ti, but making these out of stainless wouldn't take me but a day in the shop.  Supposedly a guy nearby has a similar set on his 2v bike.  I wanna hear them, and if it's something I can stand driving without being embarrassed that I'm deafening everyone around, I'll make some :)

Then i have NO idea why you would wait for these man! My brother is a welder and can do Stainless very nicely, however I havent spoken to him for 8 months since we got into a big fight. we were never really close to begin with so its not like im missing out on anything except free welding favors.... either way, you can buy some nice stainless sections from burns stainless and weld them yourself. goodluck.

Any idea on a pricing point? Or did I totally miss it?

For the Boom Tubes? They run about $700.

Not bad. I am guessing the bike needs to be tuned once they are installed.

If you open up the airbox and don't like it running lean, then yes. A PC would be a good choice.

update?

I know you have bigger fish to fry with other bikes, but count me in on a set for the 696. How do I get on your waiting list?

another interested 696. [bacon] [bacon] [bacon] [bacon] [bacon] [bacon] [bacon] [bacon] [bacon] [bacon] [bacon] [bacon] [bacon] [bacon] [bacon] [bacon] [bacon]

i believe mark is pretty busy at the moment and on the road, i'm sure he'll reply once he gets back

I finally installed the PCIII on my S2R1K and removed the baffles from the boomtubes. I haven't had a chance to ride yet but WOW does it make a difference taking the baffles out. Loud, deep sound coming from those pipes. This is gonna be fun!

baffles???  what are those?

It's what let my bike run without detonating... ;D

Howd the PCIII install go? Just plug and play?

Pretty much. Only issue I has was the software wouldn't communicate with the PCIII with just battery power, even with the engine running. I had to use the 9V adapter. It even worked OK with the map from my S2R800 loaded on there. That one had straight pipes and was a custom map made on a dyno. But I decided to go with one designed for the DS1000....

 [laugh]

dude, try to get a video up on youtube or something.  i'm going to do that once i get my bike back...  i'm curious myself to hear the sound on a drive by.

Hopefully the wife can shoot one tomorrow....

custom DS1000map?

I got some pipes to make my own "boom tubes" and if your plug bike pluged and played i dont know why mine wouldnt. We both have 06 S2R1ks.

I just want to make sure,

O2 unplugged, S2R800 or really any PCIII with the right wire harness, plug in, load map, no problems with the ECU and PCIII....

The PCIII's for Ducs are pretty much all the same with the exception of the map preloaded on them.

My PCIII was "technically" for a 800SSie. There was no specific PCIII for an S2R when I got mine.

I have the O2 completely removed , vented airbox, and BoomTubes. The PCIII goes on exactly as it did on the 800. Connects to the orange wire of the TPS.

The real test will be tomorrow when I take it for a ride...

Sound clips
1st one:  It appears the tabs holding the pipes together snapped. The fwd cyl shakes around a bit. The production pipes will have a crossover and this won't be a problem.
http://www.youtube.com/watch?v=CTYnQdDwagk


2nd one:  Just after startup, pulling away, closing throttle clip ends with me about 1000 ft away.
http://www.youtube.com/watch?v=Xof1BWe099A

oh my lord! that second clip sounds like you ran over a bunch of kids traped underneath a fence and draged their bodies all the way. That is the engine braking noise right? cause it sounds make the beast with two backsin insane.

those pipes sound make the beast with two backsing MEAN though. i assume they are basically open headers since you removed the baffels. It doenst seem like there are any problems running without cross overs either.

 [thumbsup]

It runs great, I need to change some parameters in the map down low, it's too rich.

The crossover should help with scavenging and smooth out the sound a bit...

 :o :o :o

i cant wait till this comes out for the 696.

No Sh*t!! That sound bad ass! I can't wait.

A couple of notes:

1) BoomTubes had a slight delay in manufacturing via my vendor.  Corrected and we are back on course again.  Updates for the 4V guys in a few weeks in regard to ordering with 2V'ers shortly thereafter.

2) Chris/Nakid's system is the older style BoomTubes I did.  Yes -- there have been different flavors as I went along.  37+ handmade systems have allowed myself to do some tuning / experimentation along the way.  Newer systems have a more gentle "overrun / off throttle" response.

3) Nakid's system is now "wide open".  No restrictions or baffles in them at all.  Even in this configuration, they are tolerable at low/mid rpm.  WOT -- it sounds like you are riding the chariot into the Roman Coliseum with the crowd getting excited.

4) Chris just tried a new fuel map I created for the PCIII and that I've dyno tested on a few other bikes.  It's a bit rich down low still, but we will correct via the dyno once the production 2V S2R1000 systems are in production.  As for horsepower with BoomTubes and the PCIII mapped properly -- he can answer that one for you himself.

5) Due to the wait due to the manufacturing vendor, we have done more experimentation on baffling options.  I think we might have found a nice quiet one that isn't very restrictive at all.

Thanks for the patience everyone!

I. Can't. Wait.

Just looking at my bike, i can't picture where the pipes will exit without hitting my swingarm... 

With the pipes coming out at an angle (as i believe i read they would on the production run) have you thought about an angled cut pipe? (or would that funkify the baffles)  I just think it would look sweet.

The map Mark sent me was a great start. It was not designed for the 2V, so there are some differences, namely low rpm/low throttle input. That is trial and error for now with Dyno Jet's software as I don't have access to a dyno. It is a bit rich down there. After about 3-3500 rpm, it pulls like nothing has before! It has so much more pull everywhere else in the RPM range.

Thanks for the vid, made up my mind  [thumbsup]

Hope a neighbor doesn't come over and kick the bike over if you ride home late one night.  [clap]

I am pretty much set on wanting to get a setup for my 07 S2R1K.
I read this whole post, but I have to ask when (estimate) will these be available for purcahse 4 the S2R1K ??

Late Oct last I heard....

OMG! It sounds like a furious dinosaur. I love it!

Celli

I cannot wait for the production boom tubes as well (I have been harassing Mark at motocreations for some time).

Since we are on this topic I might as well share some of my issues with fuel mapping that I brought up on TOB.

I am wanting to use boom tubes in conjunction with the Beast TPO Type R intake pods for my 08 S2r1k.  This board has brought to my attention that several other people are worried about the O2 sensor and the issues with the bike already running lean from the factory.  That being said and having done alot of research, I am comfortable that with the O2 sensor bypass ($80 from fatduc) in conjunction with a PCIII using motocreations fuel maps should alleviate any ECU issues I should face.  Luckily for me I am in Baghdad until February of 2009, so I have plenty of time to get what I want out on paper as a start to the potential problem set I am going to face in the future with the tuning on the setup I want to run with, aside from a great set of earplugs)

Any of the smart guys care to confirm/deny and check my work care to comment, I would appreciate the feedback!

Thanks for all the answers Mark at motocreations, and I promise I will stop sending you emails and let you get back to work!

Rob

No problem!

FYI: I had to change exhaust vendors as the first one flaked on me after four months of delays.  #2 is full stream ahead.  4V's are waiting in the production queue.  Just fitted the S2R800/S2R1000 pre-production units yesterday/today from the new tooling made.  They go to the production queue next week.  It's taken MUCH LONGER than ever planned (I have too many sleepless nights because of it) -- so excuse the delay.  Updates to the website will happen shortly for those on the database to start placing deposits / taking orders.  Then will make available to the general public once those systems are delivered.  Thanks everyone!

DAM! That $hit sounds mean! [clap]

Lemme know Mark if you are still interested/able to sell me some testa flanges.  I've got about a dozen requests to make exhausts, and my "machinist" seems about as reliable as the exhaust guy who flaked out on you. 

The facility has over 350 workers at the one location on the West Coast -- problem was the engineering department not having their act together nor very motivated.  Newer place is a bit smaller but is deadline driven and responds promptly and still meets my rigorous specification demands.  Night and day difference to be honest in terms of getting things done to deadlines!

Headers will be available as standalone parts in early 2009. 

One of the things that has bugged me about aftermarket exhaust systems is that if you damage something, you are essentially screwed and have to buy a complete replacement system -- you can't get spare parts.  Thus for BoomTubes riders who later damage them ala accident / tip-over / etc, we are putting together a replacement parts system to help one get their full system functioning again without having to buy everything again.

Wait, you mean you're thinking of your customers?  You're trying to make a product that stands the test of time? 

I may just have to give you my business, if that's the way you're going to be.  ;)   [bacon]

It's always good to find a "hungry" company to work with.  Unfortunatly, most of the good ones don't stay hungry for long.  The really good ones are talanted and motivated, and tough to find!


Now, about those flanges...???

Time to revive the thread. Got an email from Mark saying that they're going into production. The wife and I juggled some things around and it looks like I got the go ahead to get my new exhaust!

You're gonna love it!

Website doesn't mention these being available for the 620. Have you given up on them?

Mark/ Motocreations,

Do you have any sound clips of the 'tubes with the "Quieter baffle option"? Or how would you compare the baffled sound with an unbaffled full Arrow system? I thought others may be interested as well.

*Update*

We soft launched S2R800, S2R1000 and S4RS BoomTube exhaust systems last week to the contact database who have been so patient in their wait for a true manufactured/production system.  A couple of S2R800 and S2R1000 systems already shipped to a few folks.  Remainder will ship @December 10th in volume.  @5 days later for systems that are ceramic coated.

Introductory price is $695 and includes T304 - 1.75in OD stainless steel tubing, three-part system (headers and collector w/crossover), stainless steel spring clips, exhaust tips and all flange/exhaust collar requirements for mounting.  Free shipping for all systems ordered by Dec 31st, 2008 in the lower 48 USA.

Primary options are: ceramic coating (int/ext) for $115/system in seven optional colors.  And we are currently finishing optional exhaust tip variations and an even quieter baffle setup -- prices TBD before final shipment. (or can be upgraded later)

We are "hard launching" the exhausts this week for general enthusiasts.  Awaiting a few proofreads and pictures before pushing on the website. (and I got bombarded this weekend with non-MotoCreations demands)  We are processing orders though for the past few days.  And we will have an advertising banner in the upper right corner of this cool website sometime this week!  It was the members of the DML/DMF that helped inspire us to do these as a true manufactured/production system instead of my continual one-off systems I've been building for years.  Perk of the manufactured/production system is we had *spare parts* available that will fit without problem in case you damage your Ducati -- no need to buy an entire replacement system to replace just one component.

Per the video/soundclips -- we will have those @mid-December via  a few customers.  In general though -- unbaffled BoomTubes are LOUD LOUD LOUD - but I have 20+ customers who run them in this configuration. (I don't -- it's too loud for myself personally)  Standard baffles is civilized in town < 5500 rpm -- LOUD if you are ripping through the countryside at high rpm -- it sounds like a racebike.  The quieter baffles I'm awaiting delivery of currently, they are based upon one-off variations I have done for folks though -- quieter in town than regular baffles -- but still pretty loud when > 5500 rpm. (probably @3db quieter than regular baffles)

Important note -->  It's taken quite a bit of effort and a few false starts (various outsourced manufacturers) to get these to market.  We are proud to have a unique quality product that is 100% manufactured in the USA.  And it's just the start of many products that will be rolling out the door here in the upcoming months!

I just PM'ed you Mark.  I'm interested.  Has any one posted decibel levels for factory and various performance exhausts?  I would be really interested to see those.....I have cored stock cans minus the udder and wonder how much louder these things will be.....

Shit. Now you've got me thinking that I should just take the mufflers off my Sport 1000 and not worry about getting an aftermarket exhaust.

Although the boom tubes are not something I want for my Ducati,  I really want to commend you Mark on all that you have done here.  I can't wait to see more videos.

Thanks for the words of recognition.  It is appreciated because it has taken a lot of work to make happen -vs- continual one-off products and bikes over the years.  As for videos?  I'm waiting for the giant customer BoomTube video production -- early 2009 hopefully with four years of BoomTube stuff as customers send them in (finally!) and new customers who are getting systems here shortly.  Definitely will be on YouTube along with a few other MotoCreations videos underway for a retrosport inspired bike for myself. 

Are the baffles going to be able to be taken in and out?

Yes. 

As I see there is a bit of an update on the MotoCreations website, I just had a question about the Boomtubes. On the S4RS you see easily how much added ground clearance you gain with the Boom tubes. However it looks like the S2R1000 model has no real clearance difference compared to any other mainstream aftermarket exhaust, Is that the case? 

Also not to echo everyone else on the thread but when are we going to get some more sound clips. I am solely waiting on those before I pull the trigger.  [beer]

Interested on a set for the S4Rs w/DP ecu

You're not allowed to put aany more bling on your bike. It might explode.

They're both about the same distance from the ground, the S4RS exhaust just goes on the other side of the deep sump and makes it look higher....

Site says "base model" exhaust baffles..

What does this mean??? - Do you have a dB value?? I'm looking for something within the same range as arrows - 102-105db.. In my case, less is better than more. I dont want it any louder than the 105dB range.

Any sound clips yet???

You said you've done dyno's; I was hoping you have a sound sample somewhere..

Great work, what a fantastic sound! Not to thread jack or anything, but what causes the enormous amount of sound during engine braking? A friend of mine and I both have a '94 M900, I've got low-mount Termi's (oval CF, no baffles, runnin' a little lean still), and he's got high-mount DP (oval SS, Remus I think, no baffles and perhaps a bit rich). When he closes the throttle, there is this massive wave of sound (nothing like the boomtubes, but hey, what comes close?), while my bike sounds (too?) civilised. Is it the construction of the pipes? Or the fueling setup? Any thoughts?

Cheers!

thats either an open airbox or pods.

I have pods on mine and they sound beastly..

Nah, he's got the full lid, with both tips (removed one now, running a bit better, only the sound under acceleration got louder), and the OEM filter, while i'm runnin' the K&N filter with full lid (tried removing one of the tips, but ran very crappy afterwards)...

I don't have an open airbox or pods. I do have 2 1.5"X1.5" holes cut in the back of the lid...

if i had to guess, theres no place for the gas to expand, so the sound just comes out raw.

for real exahust systems. the gas has a chance to expand (thus queit down).

Well I just ordered a set with black ceramic coating, the quietest baffles and pencil tips.  It will likely take me until the end of January to get them installed, but count on me to record sound levels with my current cored and udderless stock system, no baffles, and with the quietest baffles Mark uses.  Anybody in the DC metro have a decibel meter?  If I had one, I'd measure dB as well.

I've got to say that Mark is a pleasure to do business with as he definitely puts the customer first!

+1!

hey. i have the termi system and it has the fit and finish that only a racer could love. i get 126 rwhp (dyn0-tuned) and it sounds great: not too loud, just a great growl. but the pipes, especially, look like sh1t, while the carbon is slowly fading, i think.

plus, hell, the low slung look of these boom-tubes is awesome. i want!

but i would like more data regarding db. there should be more on youtube. come on guys  [popcorn]

Bumping this up to see if anyone has measured db, posted sound files, youtube, anything.

Thanks!

Just in time, I guess I'll wait on new pipes until your 696 stuff comes out...

Just bought a set for my S4RS, I plan on doing a before and after pic + youtube of each.  Don't have a decibel meter or anything handy though.

If I take the video with the same camera both times, I figure it'll give a pretty good representation of the sound difference.  I run just the open udder at the moment.  Installing Boomtubes with medium baffling hopefully sometime this week.

Open airbox, open clutch, FatDuc on my setup.

Any rev requests?  Idle, rev to 8k, hold at 4k or something like that was what I was thinking.  With the udder, then the 'tubes.

No guarantee on the sound clips, I'm just trying to be nice  :)  I'll try my best to do it scientifcally.

My neighbors may end up shooting at me before I'm done.

Go find yourself an industrial park on a a Sunday to do your passes... [thumbsup]
