Bugger.... the Evil One within is speaking to me again.....and the two words he whispers incessantly are "boom tubes".....  I love this look on M1100 >> (http://www.motocreations.com/dmf/M1100BoomTubed.4s.jpg)
<<  but living as I do in the People's Republic of Victoria, I fear eternal incarceration if I I'm found to be violating noise regulations with my drive-by window-shattering mobile Thunder Box.  So when compared to Termis, how loud are we talking? Anybody?

They are loud, but Mark can make different "baffles."  After the holidays, I'm going to order another set to quiet things down a bit.

The look, fitment and weight savings are great.

P.S. is the vertical cylinder header missing in that pic?   ???

As pompetta said, Mark can make baffles to make them as loud or quiet as you like.

If you don't already know - MotoCreations are making a new line of exhausts, keeping the boom and adding bass.
Wait/save for that?

That's what I'm waiting for.  Going to be called the monoBOOM and Mark says teaser pics next month. 

He does it better than the pros [bang]

The BoomTubes look sick on the SSA bikes!   [bow_down]

Why is it that we always seem to be thinking the same things Ungeheuer.
New bikes each of us.

- clip-ons (you old Tall Boys)
- Gold wheels
- Black/Red/Gold theme
- Now thinking Boom Tubes.....

Were we twins separated by the state at birth! 

Great minds think alike mattyvas [beer] ....and good taste  [wine]...well you either have it or you dont  ;) 8)

<whispering into wrist>

Shit. They're onto us. Take em both down. NOW!

</whispering into wrist>

quiet low bass boomtubes? WANT. Love the low thudding sound of termis, but Boom tubes are way to loud.

if you research the testing method and db limit, I bet Mark could test some baffles that could meet your limits.

he said it would be the 95db range max. im assuming thats as loud as it gets for the regular way they test for sound. at a certain distance, at a certain RPM. it would certainly be above 100db while riding...which is fine for me.

My clutch is def. lounder than my boomtubes at idle.
Cruisin around on the street the bike hsa a def. growl to it, but nothing worse than a HD.
On the tollway under throttle is where the pipes really scream (and sound soooooo good)  ;D

Look under the spring/shock

Having gone from a Termi system to a "sort of BoomTube" (Mark made me some extensions for my Termi headers), there is a considerable sound difference.  Not only are they louder, but they have a sharper tone.   They sound very cool (IMO) at idle and really, REALLY scream when you flog it.  They will turn plenty of heads on decel.  Exactly what I wanted, but I am sure it is not for everyone.  In referencing my bike and the setup I have, the volume is a little louder then the stock udder by itself (just volume, BTubes have much better sound quality).  I believe Mark can baffle however you want them (I told him that I wanted mine loud), but with the regular boomtubes, you are not going to have that low, muffled growl that Termi's give.  It is gonna a much more distinct thump at idle and window rattling @ 9000rpms.

...and y'know... right after I pay attention to the Invisible Evil Guy who sits up there on my left shoulder, pretty soon I begin to hear the tedious doubting comments of Invisible Captain Sensible counselling my from his perch on my right shoulder..... and CS is saying things like "sure,it looks cool.....but what happens to backpressure, hmm?"  and "how come Ducati needs all that pipework if it does nothing?" and "whats the ECU going think about not having its lambda sensors reporting for duty?".  Yeah, I know Captain Sensible is a party-pooper but he does raise some valid concerns.  And all the while, IEG keeps whispering "boom tubes........"

Tell Capt. Sensible to fist himself.

Any of the pipes with baffles are going to have no problems with back-pressure, and Mark can weld in a lambda sensor bung pretty easily.

How about starting out with an experiment or two or three?

1 Like my dealer's head tech tried with no issues (not on a Monster, but...) Unscrew the O2 sensors and tape them somewhere up where it's dry. Plug the holes, of course. They'll read LEAN and ECU adjusts accordingly. Smell the exhaust to see if/how far off it might be.

2 Ride without cans for a while, to check out how it runs without back pressure.

3 Both of the above

Maybe not the ideal set up, but it might give you a few ideas or valuable insight.

Captain Sensible and The Evil One have a well balanced sadomasochistic relationship, so I'm sure they'll arrive at the fisting arrangements in due course  [laugh] [laugh]
I never thought of that.....  Boomtubes with lambda provision...  the DP ECU would be non-the-wiser  [evil]

Damn Obsessed? ....now I have an external Evil One leading me further into temptation...   ;D 8) ;)

M1100 BoomTubes have twin 02-lambda sensors.  Ditto for tuned baffles.

Give the sound levels you are looking for, I'd suggest waiting for the MonoBoom upcoming. (although it will be more costly due to more labor, time and materials to create)

02-lambda adjustment?  In the "bat cave" work is being done now on that.  Solidstate, LED display and adjustment buttons to allow for modulation.  It even has a "heartbeat" to show the device is working!  Purely alpha at this stage and we want to do some riding on it via the "test crew" once a beta version is finished.  Will do a version for the Siemens ECU and the Marelli ECU.  More updates on this later in January in my sponsors area <---- (left side of screen)

I think I just heard a single gun shot. 

You are so boned.  [laugh]

Obituary:  Tuesday December 22, 2009.  Captain Sensible, long suffering adviser and ignoree finally lost his battle for relevance and passed away suddenly.  According to his nemesis known as The Evil One, there were no suspicious circumstances.

He will be sadly missed (by my bank balance, credit cards and the makers of KY).

RIP.

Lol, so it's boomtubes? [laugh] 

Out of respect for the recently departed, I couldnt possibly comment  ;)


That... and the fact that I think I ought to wait to see how the forthcoming MonoBoom shapes up before I pull the trigger.  << Insensitive choice of words there, I'm so sorry  :-[.

Aww, dude. Too soon, too soon!  >:(


 [laugh] [laugh] [laugh]

..... but if I do end up booming my monotube.... the (other) cool thing is that there'd be room to fit one of these >> http://shop.revercorsa.com/catalog/product_info.php?cPath=1_52_79&products_id=212 (http://shop.revercorsa.com/catalog/product_info.php?cPath=1_52_79&products_id=212)  <<  [evil]

dude, you got the fever!!   [laugh] 

I thought the DP ECU eliminated the use of the O2 sensor anyway...

apparently not. only on the full termi system for the 1100.
we talked about this in another thread i think. stock, slipon DP ECU (with o2) and full DP ECU (no o2)

but.... found a company working on a full remap of the Siemens ECU. will let you know as I learn more.

Nope.

Seems like neither DP ECU eliminates the o2 sensors >>http://ducatimonsterforum.org/index.php?topic=33013.msg576814#msg576814 (http://ducatimonsterforum.org/index.php?topic=33013.msg576814#msg576814)

You guys and your O2 sensors....and your lambda smambda....and your ECU's....and your back pressure.  Face reality boys.  Our bikes are much too fast! And much too pretty to grace the passerby's with nothing but a blur.  Make them loud, make them look good, and ride by slow for the world to admire.  Oh yea, and try your best to act like you don't notice!

so maybe this was answered already...are there boomtubes available for the 696? I don't see them on the website. 

Somebody on another post asked how to mount an I-Phone to a Monster. Are you serious? Get some Boom Tubes and you will be hearing the sweetest music on the planet! [drink]

Has Mark said if the new Mono Tubes will be available for the S*R series, specifically the S2R 800?

" We will do the big single outlet the same as were the BoomTubes exit.  It's @10db quieter and a louder "boom".  It also weights @4lbs more than BoomTubes due to the packing within.  No pictures until we are done testing.  I'm building a set for the M1100 and Hypermotard currently and will test on those with the "test crew" for awhile. We are probably 90+ days out before we get these finished. I also want to test a carbonfiber tube section as it resonates differently.  FYI -- I won't be doing these for the S4RS/T at all -- we will only do for the M1100, M696, Hypermotard initially and followed by the S2R800/S2R1000 later."

Looks like your in luck, I was checking on it for my S4RS/T

I am waiting very impatiently to see what these will look like

i installed boomtubes on my s2r800 today. holy crap they are loud! a little to loud to be honest.

I've been considering these myself for my S2R 1K. Do you notice any performance differences?

i only rode it around my neighborhood as its not insured right now, but with no other modifications or even a tune, the low end does suffer. but thats expected without a tune.

So another $500 for a tune or $80 for an O2 manipulator. What do you think it will take to solve the problem. My S2R runs sooooooo dam good stock that I'm almost afraid to mess with it. I'm also thinking of just purchasing the Marving Cat eliminator anong with an O2 manipulator for about $400 total.

ill probably get a powercommander 3. i cant remember if they make one for s2r1ks. i got the exhaust for looks more then anything. mark is working with me to lower the noise. apparently running lean and cold temps greatly affect loudness.

Boooooo!!!! 

Is there any alternative to the DP ecu for the 696 in regard to custom tuning. I have a local shop with all the equipment but Don't want to fork out 1200 for the DP ecu.. If I were to get the MonoBoom I would definitely want to tune my bike.

There is a lot of info for the S*R bikes but not for the 696/1100 in terms of tuning. I need my options!!

M696/M1100 were the first Ducs to be running ECU/fuelling by Siemens....  and whilst there are options for previous Marelli systems.... I've heard of nothing so far for 696/1100.  I'm sure somebody somewhere is working on it right now though  [popcorn]

So for motocreations exhaust my best bet is a DP ecu, which is or is not custom tunable?

DP ECU is not custom tunable (at least not until somebody figures out how to reflash it).
