What would you do and why?

I went with boomtubes. The Exbox looks just like the udder. The tubes clean everything up.

  I wanted Boom Tubes on my S4RS project but never could a response from anyone. Left three phone messages and a couple of emails.....nothing. So I bought the Exbox. I'll put in a plug for Bellissimoto here also. Called a few dealers about the Exbox and they said they were out and couldn't get them. Randy at Bellissimoto made a call and it was at my house in three days.

Seems like getting your hands on Boom Tubes is a bit of a challenge right now. I think this option may be even better looking than both Boom Tubes and Ex-Box

I would go for the Quat-D! It gives an agressive look on the bike, boomtubes makes the bike look too naked.

Too naked? ... Did you say too naked? Nothing is too naked unless we decide it is!!! Were the Germans too naked when they bombed pearl harbor?? 

HUH??? wtf

Forget it, he's on a roll

If pressed to choose between Exbox and Boomtubes..... I'd choose Exbox.

Boomtubes do look cool its true, but I'm of the opinion that the Exbox will be less inefficient, especially with baffles fitted.

I'd like to see some dyno numbers vs stock  [popcorn].

Too naked? WTF? More efficient what way? Baffles? Maybe ther should be stricter rules as to who they let in here.

I think a lot of people(myself included) have found that very non-restrictive exhaust can cause problems....

Installing even a small baffle has made a noticeable difference in how my bike runs, and that is after a tune. The tuner even suggests that the exhaust was causing issues with the tune.

Everyone seems to suggest the boomtubes aren't restrictive at all, and because of this, offer less of a performance gain but more of an aesthetic look.

No one has really compared both aide by side, and no one seems to know which exhaust system(termi, arrow, boomtubes, etc) is really the best....

I had a choice, and I chose boomtubes.

*less weight
*less chunky (visually)
*more configurable (tips, ceramic coating, baffle size)
*mean sound
*etc.

whats with the talk about efficiency and baffles and whatnot?  boomtubes ARE baffled.  they just aren't technically muffled.  they provide plenty of backpressure.  I am able to run boomtubes with an open airbox lid without a custom ECU, and while I'm sure its not perfectly tuned, a little tweaking on the TB adjuster screws has it running very strong and reliable.

Exbox - I've owned one. I bought it because it's the most out of the way. You can really see the rear wheel. It's centralized mass. It sounds good (subjective) and it is the simplest. Also, if you dump your bike, your exhaust will probably be fine.

Slightly negative it visually makes the bike look a little square at the front which isn't great but it's worth it for me because it makes the tail look awesome.

I do think the Boom Tubes look a bit sexier but I heard there's a hell of a wait on getting your hands on some Boom tubes and I also  heard the Boom Tubes are much louder than the Ex-Box which could be a problem for me as I like to go for weekend morning rides and live in a suburban subdivision where they already complain about the noise from my bike. If I make it louder I could have a full scale riot on my hands. Anyway I just scored an Ex-Box at a decent price so I'm gonna try that out. I'm thinking a Paul Smart or Sport 1000 next year or the year after so that will probably get the Boom Tubes as I like the naked look and prefer cans on women.  ;) Then I can compare since I aint selling the Monster ever unless its to buy another one.

What do you imagine happens to the exit velocity of exhaust gasses if you place a restriction (baffles) within a straight pipe? 

Why do you imagine cans are significantly larger in diameter than the pipe they service?

Like I said, Boomtubes look very cool [thumbsup].  But unless you're prepared to make max.noise, I'm questioning their efficiency.  Whilst not looking as neat, Exbox at least has some expansion volume.

Dyno numbers?

Anybody?...........................

Thats a beautiful bike EvilSteve  [drool]

Thanks, don't own it anymore. Kinda wish I did when I look at this photo. ;)

I have an M1100EVO now, looks similar.

Exbox for the win!

Had full termi, went to bts.  Lost 2 hp,  lost 10 lbs up high,  bike feels a ton lighter.   I think it was worth the loss.  I could probably get it back by altering the baffling, but it's plenty good for now.   We'll see once head porting and high company piston time arrives

So I have to decide here. Do I go with Boomtubes or Exbox. IMO Boom Tubes are more aesthetically pleasing to the eye without that box and loud (better sound??) which I like  [evil] but could also be a little bit of a problem.  [leo] But there is also the performance issues discussed here. Will my bike run worse with Boom Tubes (I somehow find it hard to believe that they'd be that popular if your bike ran worse and that Mike would be making a mod that made your bike run worse)

The thing is I can get a great deal on an Ex-Box right NOW as opposed to paying $200 more and waiting until Dec/Jan till I get the Boom Tubes. But it is almost the end of riding season here anyway so I could wait for Boom Tubes... Damn I hate making decisions like this.

I think if I get the Ex-Box I'll always wish I got the Boom Tubes but somehow I dont think I'd feel that way about the Ex-Box if I got the Boom Tubes.

Somebody convince me already so I can shutup about this!  ???

I have three issues with this quote.

1) "It's the most out of the way." - Um... no? It's larger than a comparable set of BoomTubes, meaning it's MORE in the way. It's more out of the way than, say, a stock exhaust or a direct aftermarket replacement (Zard, Arrow, Termi etc.). To say that it's the "most out of the way" is, frankly, bullshit.

2) "It's centralized mass." - Again, no. Comparing the options of Ex-Box - vs - BoomTubes: you've got a box that weighs more hanging farther off the back of the engine. Once again, it does a better job of "centralizing mass" than a stock exhaust or comparable system. But which is better? Having more mass closer to the back of the engine? Or having less mass hanging off the back of the engine and less mass overall?

3) "It is the simplest." - In what way? Horiz Pipe + Vert Pipe + Box + Baffles + Tips < Horiz Pipe + Vert Pipe + Crossover Pipe + Baffles + Tips?

ALL OF THAT BEING SAID!!!

My experience with BoomTubes on the DS1000 engine in my Sport 1000:

Mark is awesome, but it's gonna take you a while to get your Boom Tubes. They're gonna be everything you want them to be when you get them! But plan on having some delays. It's just a function of how they're made.

I (personally - this is "butt dyno," no real numbers) feel that the baffles in BoomTubes (should you ask for them) actually reduce top-end horsepower by a smidge. I have "medium-loud" baffles. The bike still has all kinds of grunt. That said, it gets a bit "winded" above about 6500-7000 rpm. It's nothing you're going to feel in "everyday" riding, but it's there.

I have the "staggered" tips, where the front one sticks out a lil further. That front tip is a bit ground down from taking hard right turns. Like "at the track" hard, not just "turned right at a stoplight" hard. So if you ride the bike in anger, be prepared to scuff the tip. Or have Mark adjust the length of the tubes/tips for you to avoid that problem.

Also: having "medium-loud" baffles, the bike is LOUD. I know immediately if I forgot to put in ear plugs. I can also tell if one of them isn't seated all the way.

Still: when I fire up the bike and hear the beautiful noise it makes? Yeah, I get a huge shit-eating grin.  ;D

When I see a tunnel approaching and I downshift? Yup. Same smile.  ;D ;D ;D

My vote: If you want sound and that last 1/10th of performance, get an Ex-Box.

If you want sound and the look of BoomTubes and are okay with sacrificing that last little fraction of power, then by all means get BoomTubes.

[laugh]

Listen to that guy, he's louder.

I also had this debate for about 2 seconds. Mark and I exchanged emails for a few weeks and got everything settled. I was never dissapointed with the decision. I loved my bike with the boometubes until the day I sold it. It just makes the bike just that much more unique and eye catching. Did we mention the sound? You just can't compare them for the joy they bring you. If you're willing to wait, they are well worth it.

Okay I saw this disclaimer on Motocreations BoomTubes Page

note: BoomTube exhausts are not DOT/EPA complaint. They are for "off highway use only".

What does this mean for me? I dont believe I am required to get my exhaust checked for my motorcycle like my car so unless I'm being all environmental do I care? Is the Ex-Box DOT/EPA compliant? Am I going to get slack from the State Highway cops or just tree huggers throwing stuff at me? I heard Boom Tubes get you a ticket in New York City what about Chicago?

One more thing has anyone heard if the EPA is going to start making Motorcycles get their emissions checked? If so what does that mean for people with Boom Tubes if and when that happens?

Absolutely nothing. That is just a legal disclaimer so that they don't go after Mark. I rode my bike on the highway in various states and the only look I got from LEO's was in appreciation, even when I got pulled over.

So how loud are boom tubes with the quiet baffles?

The reason I ask? A H-D Sportster with 1.75" drag pipes is so loud it makes me physically ill. I bought some cheap universal 8" long baffles and it put it back down into an acceptable range. I hate the sportster. Total wast of my money. I should have waited till I found the Monster I want...

Since I am leaning strongly towards Boom Tubes this is a good question. There appear to be 3 sound options. Loud, Regular and DB-Killers. I was thinking Regular which I assume will be much louder than stock or my current Remus Exhaust. Anyone have any insight on these 3 options? Anyone try the DB-Killers how loud is that compared to a stock or Remus/Termi exhaust? I figure the Loud will definitely be too loud for me and my suburban hood. I'm in the Soccer Mom crosshairs already.

Different stokes...I'm an ExBox guy:

Really... both are great choices otherwise this poll/debate would have no need to exist.

I had an Ex-Box and now have Boom Tubes.

Butt dyno senses no difference between the two.  Good enough for me.  If I wanted max hp, I'd get a Gixxer or a 'busa.

Regardless, I'll prolly replace the Boom Tubes in the Spring...time for somethin' new.

I've owned 3 aftermarket exhausts for my S2R800

1) Quat D Exbox - POS fitment - Returned it for a full refund back to motowheels. These things are very restrictive and weight almost as much as the stock setup.

2) Exchanged said Quat D for the exhaust that is quite possibly the exact opposite in terms of fitment (Arrow Full Race system). That thing is designed so perfect you dont even have space for RTV at the slip fit joints. I put a lot of miles on my bike at this stage so I got really tired of taking off the exhaust every time I had to change a rear tire.

3) After 7 tire changes, Arrows got on my nerves, bought a set of boomtubes. I was one of the first orders. Fitment was better ONLY because unlike the Quat D's I knew the person accountable (Mark) and was able to send them back. After 2 trips back to Washington state, we got the fitment working to run on my bike. The setup is so extreme that unless I had my fit and fueling perfect, the bike would backfire. Put in on the dyno and the operator had a REALLY tough time tuning the rear cylinder due to the shorter exhaust run. I'm lucky i paid for an advanced map with independent fueling for the horizontal and vertical cylinder. The vertical fueling was night and day different than the horizontal.

I have to stress that this setup DOES lose top end like most people say. I can tell between the arrows I previously had. I'd say at least a 2-3 horse difference.

BOTTOM LINE. Theres a lot of baggage that comes with boomtubes. A lot of factors have to be just right for the bike to run properly. If they are, you're going to enjoy your bike,  but If you're not a detail oriented person I'd stick with the quat d. In terms of fueling, the quat d is a LOT more forgiving.

Example: I had one exhaust gasket blow out a month ago (the stock ceramic gasket at the header connection). I lirerally had the sandwiched ceramic blow completely out. End result of this was a fat blue flame spitting out of my 'tubes on decel. Some people think thats cool..I dont.

BTW.. DONT get 'tubes that are not ceramic coated like I did. Mark's got the tolerances set for the coating on the slip fits coming off the headers so if you dont, you're going to have a tough time sealing up exhaust leaks.

I recommend Wurth exhaust assembly paste for the slip fit connecions. its harder to come by but Permatex Ultra Copper RTV will just blow off the stainless steel (2 months of dicking around with exhaust leaks at least taught me at least that much)

Dont take this post as a negative towards boomtubes. They're good exhausts. But they are a lot more radical than some of the others. And bear in mind I have TPO Pods and Boomtubes. The setup is about as radical as it gets.

There is a reason you don't see this type of exhaust on any pro race motorcycles, just sayin.

I think everyone is missing the point here...

The poll is flawed.

Boobies.

Xbox on a s2r with same mods hyperstack, pc, cams, made 7 less hp than btubes on my 1100 with pc, cams, stacks. Termi full on 1100 made 2.5 more horses, but the power curve was more peaky and had less area under the curve overall.   

But dyno bt feel the best to ride,  with almost no weight compared to the termi set.   Xbox is heavy for what it is. 

My bt are oversized (1.75" at header to 2" each at exit) , so i would expect less performance slight for regular sized tubes.  They are moderate baffled, with less I could probably squeeze another horse or 2.

Yup. Thats my experience too.  One fuelling size doesnt fit both.

Exactly.

on my s2r1000, 93-2=91. huge difference for a pro racer, no difference for a schmo like me. i do not think we should worry too much about miniscule differences in hp. i also doubt any of us ride these bikes to their limit, especially on the street.

Now this debate is really getting interesting.  [popcorn]

well, your question was basically "choose between megan fox and evangeline lilly" - what did you expect???

I did forget to mention that at the time I installed the BT's, I also opened up the airbox. I had to get the PC custom mapped to fit. They spend a long time getting it perfect, but they did an awesome job and it ran super smooth.

So if I get Boom Tubes on a simple little '05 620 am I going to have to do anything with regards to tuning or modifications. Is it recommended if not required?

It's definitely required to tune for them. 

I would say that if all you're doing is the exhaust, then no, you likely don't HAVE to do any tuning. The limiting factor on how much air your engine moves is still going to be the intake. It will probably run a little better if you get it tuned, but it's not likely to hurt anything if you don't. Hell, they're even available with an O2 sensor bung if you want/need it.

If you open up the intake at the same time, then yeah. More air in + more air out = need noticeably more fuel.

All reasonable points you make there. 

I'm not worried about "minuscule differences", but for me any mod which resulted in ≈2.5% drop in HP is something I'd wanna know about prior. I think its worth noting that whilst systems like this do have great visual appeal, and obviously (especially in the case of boomtubes) shave off weight, in the absence of any actual measurements to the contrary, anecdotal evidence suggests that these aesthetic/weight benefits come at the cost of a little HP.

Weight savings BT vs. M1100 Termi full system. ~7 lbs.  HP loss 1.9hp with medium baffling.

No anecdotal evidence, real numbers only.  the curve is fatter across and less peaky, so it feels better than the full termi did.

For some of you guys with larger displacement engines I can see these horse power issues as points worth considering. But if horsepower was one of my bigger concerns I wouldn't have gotten a 620. This thing just needs to be fun to ride, handle well and look good. When I get my next bike which will probably be a Sport 1000, Paul Smart or a Monster 1100 EVO the power impact of the exhaust will probably be a much bigger consideration. So for now the Boom Tubes seem to be the way to go.

My advice is order them now and maybe you'll get them for next summer.
I canceled my boomtube order after close to a six month wait. How are those kickstands coming?  [roll]

i agree. you should know all the facts, then decide. i was aware the power drop, but i decided to go with the boomtubes anyway. i do not go to the tracks with my bike (not yet, anyway).

also, the boomtubes are a long wait now because of all the misfortunes that happened around mark this year. 

Shit, if you are already planning on getting another bike why spend a grand on your current bike? Pocket the grand to put on the new bike! That $1000 will go a hell of a lot longer way on a new/different bike than it will on the 620.

I have considered this and if I was getting a new bike next year then yes for sure I wouldnt be spending a G on new exhaust but really I wont be getting a new bike till at least 2013. Also half the money for this exhaust is coming from selling my old exhaust anyway. I dont plan on selling this 620 so I want to be completely happy with it. The next bike will probably be a Sport 1K or Paul Smart (hopefully) so I'll still be riding this bike often. I need to be happy with it.

That makes sense if you are a couple of years off anyway. Hell, even if you did save the G now you'd probably find a way to piddle it away between now and new bike purchase time.............might as well spend it now on exhaust stuff!! [evil]
