So what do Buell XB roadracers do about an exhaust? I've done much research and found few answers. | ||

Hey, Chris, a lot find a used Buell Race muffler. They don't make them anymore, but there are always some available on eBay or even here in the classifieds. Head pipes seem to be fine. Seems like the mufflers go for around $400+/-. That's all I have. Micron used to make a system, but I think they are out of the business of exhausts or something. | ||

Tom Beson used to be the "go to guy" before health took him out of the exhaust business. IF you can find one of his exhausts you're gonna be great... except they ARE LOUD and that might limit you on some tracks where they do sound monitoring. PM me if you're interested, I have an email from one of the Buell guys who has one. It doesn't have oxygen sensor ports so you'll have to use an ECM that doesn't require one... or weld one in. Otherwise Al at American Sport Bike bought up the tail-end of the Micron production run. THOSE are the better pipes as evidenced in his "Exhaust Shoot Out" Shoot him an email. If you're interested in a Beson, I can see if I can find that email. | ||

I found it - it wasn't an email, it was a Classified - "Hogs" is selling his Beson. Apparently it HAS an oxygen port welded into it. He claims it's titanium but I'm not at all aware that Beson made anything but Stainless. http://www.badweatherbikers.com/buell/messages/21/414181.html?1228692794 He has the later version with the slip-couplings - it'll last a lot better than mine without the couplings. I have had to weld it a couple times now to fix cracks. Again, the Beson is LOUD - but it is probably the lightest racing pipe you'd consider putting on the bike. A LOT of thought went into its design and it DOES make good power Did I say it's LOUD? (actually even in racing, loud isn't always good from a PR standpoint) (Message edited by slaughter on December 21, 2008) | ||

Drummer will do all of what the micron or race kit muffler will do. People are using them with great reliability. | ||

I run a Drummer and have been very happy with it's performance. | ||

I have a beson pipe for sale. It has been repaired a few times due to cracking. This pipe is great for heavily modified engines when used with proper tuning. for less modified engines, I would recommend Micron for full system or Drummer for slip on. Seth | ||

We did some comparison testing of the Beson on the same engine/same day on the dyno and it really DID perform better than another (nameless) tuned system and better than the factory race system. If you used a Beson, you really would have to have slip joints put in halfway between the exhaust flanges and the collector. That seemed to keep the final version from self-destructing. Geeez Seth - now you have me thinking... the local speed shop has offered to fabricate me a muffler for my Beson. If nobody else takes an interest in your Beson, I can take it off your hands as long as it still bolts up OK | ||

Steve, let me know, I have the three inch muffler version. Seth | ||

The thread title was Best choice for race exhaust? and the question was "So what do Buell XB Road Racers do about an exhaust?" So, Dana and Ralph when you say say Drummer will do all of what the micron or race kit muffler will do. People are using them with great reliability.- I run a Drummer and have been very happy with it's performance. Is that on a race only bike and that you are using the stock header with your Drummer? Please don't get me wrong, on the street I like my Drummer better that the Micron, but it's not a race exhaust. We have two 90inch XB's out there both identical except for the exhaust. One makes 126 at the rear wheel, the other 115. So I can tell you from experience, there is no way we can get the V/E numbers we want for a Race Only bike using a stock header and a slip on. I guess what I am asking is if we can try and control out passion and please keep our answers on target? The original question was about a race bike on the race board. The BMC is guilty of causing some of the confusion by calling some of their over the counter performance parts "Race Kits, etc. In real life the only real Buell Race Only parts come from that section of Buell Race catalog or direct from Henry Duga at Buell. Again the I love my Drummer and the Great Exhaust Shoot Out pretty much supports that it is about the best slip on you can get. Thanks for listening Terry JT&S Performance | ||

In truth, you can call Duga directly, they may be able to steer you to the Burns system that was used on the XBRR. I think Burns made an exhaust suitable for use on the XB. I can't help but think that the unmarked prototypes we've seen on a few of the 1125R's might be Burns (just looking at them) - specifically the 1125R at the IMS sitting on display in "as-raced condition." | ||

Buelldyno_guy, Good points. The definition of "race" allows for lots of latitude. I am running a Drummer w/ stock head pipe on my race only bike which makes 96-97hp running stock 12 pistons, heads, etc. For me the advantage was no trick black box or tuning, just the over the counter race ECM which won't put the bike on the front row, I know, but there is virtually no maintainance on the bike at this power level. It's lots of fun and the bike still has more power than I have ability! www.racingwithralph.blogspot.com | ||
| Babyhuey |
so which is the best exhaust for a race bike. it sounds like its either the beson or the micron. or does it just depend on your sound level limits? | ||
| Alessio66xb12r |
to Terry : what kind of collectors diameter do you recommend for 88/90" motors ??? i know there are many things involved like ports , throttle-body exc.exc. ....just to have an idea. right now i'm using stock 43mm collectors on my 88 and with that the race kit muffler works fine but i think i'm leaving some hps on the table because of my headers. very cold and always rain rain and rain again no way to go to some track and test the new map and the upgraded pump. thank you in advance bye Alessio | ||
| Buelldyno_guy |
I would have to measure a Micron, but I know it is all hydra formed and increases almost .250 inch between the header pipe at the head and the muffler intake. I may have seen a Burns and not have known what it was. but most of the real performance pipes all have headers that increase in diameter in each section and those sections are a specific length. I am sure they were all built to a V/E formula to maintain the exhaust gas V/E numbers. Specific shapes and bends are required for specific purposes. Drag, LSR and RR bikes all have different torque requirements so they all have different exhaust systems to meet those requirements. If your interested in a Micron Al at American Sport Bike still has quite a few, as he bought up the last ones he could find. Terry | ||

I dunno about the best choice, but I am runnning a Buell race can w/ ecmspy custom tuning. My goal is to remain as near stock as possible, so as to hopefully keep the costs down. | ||
| Alessio66xb12r |
thank you | ||

Terry, I don't look at the Micron as a race exhaust either for the matter. Just great street pipe like wise the Drummer. The Micron didn't beat the Drummer by all that much and the Micron had more testing prior before the shootout then the Drummer was my Impression. So what do Buell XB roadracers do about an exhaust? I've done much research and found few answers. That was the original question. And it was directed at what Road racers use. So I am on Target. Paul James and many others are using Buell's race Muffler. They are getting hard to find. My statement regarding the Drummer wasn't out of passion but rather what is really a good product and is readily out there for you racers is all. | ||
| Artic_12_r |
I dont mean to get off topic but is anybody running the Daytona Twin Tec as part if the race combination. I have an 08 12 R with the Race pipe but a little decel pooping. Im trying to get it ready for track day. | ||
| Alessio66xb12r |
i think collectors are the key more than the muffler | ||
| Babyhuey |
i think its the position of the collector thats the key point. (Message edited by babyhuey on December 23, 2008) | ||

Just caught this post, and Yes I still have the Beson Header/muffler IF anyone is interested in it... | ||
| K3xb |
Geeze! Anyone for opening a can of worms? I'm sort of shocked. It seems like the answer is that I have a choice of tracking down one of two systems that are no longer in production or a slip on over stock header pipes that are not of equal length and therefore much less than optimal. One has to wonder. There isn't anything out there in the way of a new, readily available full system that works well for roadracing? I've seen Termigioni, Fairweather and Ti Force, but no one knows about that stuff or if it can even be had here? I never imagined that a simple 2 into 1 race exhaust for a Buell could be such an impossible item to find. | ||
| Slaughter |
Yes there ARE full race exhausts suitable for the XB - Give Henry Duga a call, he should have references for you. Hal's also fabricates their own. | ||
| M1combat |
I'd go with the Beson if it's really a track only bike and you'll be doing engine work later. If you ever want to ride it anywhere else (and on the track) get the Drummer whether you're going to do engine work or not. | ||
| K3xb |
Thank you Slaughter. That was the advice I needed. I'll make those calls. I'm thinking that the Beson would be out, since just about every race org has decibel testing these days. (Message edited by k3xb on December 27, 2008) |
