I've had some guys ask about doing an exhaust for the XB bikes, how much interest is there for it? http://www.badweatherbikers.com/buell/messages/171 43/604584.html?1290101193 | ||

Do you have a design in mind? I would be interested pending looks, sound, power curves, and price | ||

I would personally like to see a short can. being minimal and not bulky like the Stock exhaust and or drummer for example. Short enough to the length of the bottom crankcase and delete the chin fairing. I wonder what your thoughts are on a system that is 2-1-1 or even 2-1-2 using stock headers. Carlo | ||

i think it would be cool, i dont have a need for a new can, but the one on your 1125 sounded good at homecoming! | ||

I'm open to suggestions for design. I do custom exhausts for the 1125 right now and I figured there's a little larger market for these. I don't own one yet, but if there's demand for them, I can certainly give it a go. I can't promise the same gains that I got with the 1125 pipes, but I should be able to come up with something that works. | ||

If I sent you my Beson, could it be cloned but with a FUNCTIONAL muffler? It's just way too loud (and yes, it's a race-only bike) We're not racing in December. | ||

Post some pics of it so I at least have an idea of what it looks like. We'll see after that, but I won't make an exact copy of someone else's work. I haven't looked at all the data yet, but from the previous shootout, it looks like the highest hp/torque numbers from the stock headers was around 103 hp and 90 ft/lbs or so. I don't know that I can improve on that, the highest looks like it was the micron pipe, but that's a full system. (Message edited by d_adams on November 18, 2010) Is this it?

I was thinking of a full system. The Beson was the best thing tested but it's just too dang loud. I certainly understand about cloning something - I just need something ELSE. I might have a Burns can just welded and adapted. | ||

You need to make sure you have enough volume in the muffler so you dont get exhaust reversion (scavaging) , that is why with the short pipes , such as the Jardine , you get surging in closed loop mode . And that is why big mufflers , such as the Drummer , work so good , because it has a large volume . It can be done by lengthening the header primary tubes , or a large volume muffler . For XB12 you need almost 2+ gl. of volume = cyl. volume , and the muffler outlet cant be to big , 2" max , or your bleed off rate will be to high . There is a reason for the large mufflers on Buell XBs , and it has alot to do with the open loop/closed loop FI . That is why short pipes run good at wide open throttle /top end , but run like crap riding around town . I think it would be cool if someone would make a complete system in the U.S. , you need to look at the euro XB headers (such as Trojan), and notice the lengths of the primary tubes , and copy that , then you might be able to get away with a smaller muffler . If its a race only system , and you dont care how it runs around town , you can make a short system , with good wide open/top end power . | ||

These are from the 1125 shootout if you guys never get over to that section. Top hp and top torque. I might be new at this, but I do get it done.   | ||

what about . . . stock headers, 2-1-1, extend a 90 degree pipe to the rear of the bike along side the crack case and loop back to the front ending with a baffled end pointing forward. Essentially extending the length of the exhaust. Not sure how that would look I kinda like this here: http://www.supertrapp.com/product_sections/detail. asp?CatID=30&ItemID=443-2010 If anything, 2-1-2 using a similar baffle setup and extend towards the rear or as it would fit best under the bike and a little angled outward. In any case. just thinking here, if you created a setup to accept the supertrapp, wouldnt the disc design help with the previous mentioned problem on exhaust reversion? | ||

Oh , you build the KEDA pipes ! Those are nice ! I dont know that much about the ECM,s on the 1125's , but I do know they have two O2 sensors compared to the one on the pre 2010 XB's , and they may have a better range to deal with closed loop issues with short pipes , not to mention being water cooled and being able to deal with engine temp. better . But even with your system on the 1125's , you have pretty long pipes , compared to the XB,s . If you could copy the Beson header design , with a can type muffler , but not straight through , open inside for more volume , that would be cool . Plus you have access to a dyno to test . I think you will find the XB,s a little harder to tune a pipe to run good all through the operating range , because of being air cooled and the limitations of the open/closed loop system . But I hope you make a system , because there is very little choice out there for XB owners . I would buy one . | ||

I have wondered about the SuperTrapp muffler and reversion myself , I would like to test one out and see . You know the first tuber Buell S1 race kits had a SuperTrapp muffler . | ||

At this point, I'm just tinkering. There's some calculations I need to do to sort all this out. It's not like "oh, yeah, I'll just throw this together and it will make 110 hp" or anything like that. There's some stuff you can tune into or out of a pipe if you know how to design it. I'm just an average guy doing this in my garage. I don't have a flow bench or dyno at home, although that would be nice. I do some stuff on a calculator, get a rough idea on what I want and see if I can make it work within the space limitations I have. I wasn't worried too much about how loud the stuff was for my 1125 initially. The way I built it, I assumed it would work the way I wanted. Yeah, it's a bit louder than what I thought it would be, but to me, it's exactly what I wanted, especially after I heard it the first time. Nobody even got to see the first grin that hit my face, much less the happy dance around the bike after I did the initial startup/run video. Yeah, I laughed like an idiot after I ran it for probably 2 minutes straight. If you've heard one in person under a load, you know exactly why I did. It's intoxicating. Every ride, I mean, EVERY ride, I laugh somewhere along the line. All it takes is just a little bit of a twist on the throttle. | ||

It is. It is also not very hypermiling friendly!  I love that pipe you built me, despite it being too damn loud. | ||

i think something like the remus or reverso front exit exhaust. a nice, reasonably priced front exit exhaust would be cool... just a thought.    | ||
| D_adams |
That first pic, wish it was a little bigger. I make something similar now with 4" cans but it's spread out at the back a little. Those look like they're set straight side by side and maybe 3" cans. I've considered doing 3" cans for a while just to tuck it up tighter to the engine on the 1125, maybe this will push me over the edge to try it out. 2-1-2 is probably the best bet for this motor, I need to get busy with the number crunching soon. | ||
| Kdogshirow |
Good luck to you . Be sure and post when you have pictures and info , cause I want one ! I have seen and heard your other work and I am impressed . And I am like you , loud does not bother me , I like it !  | ||
| Thealpacca |
i had a remus and it was crap, the brackets broke off, i got one made by a chap who lives near me, he's a bueller too,i think he posts on here, or ukbeg, albert666 , his sutff is works of art | ||
| Kdogshirow |
I wish you could make this one , this is a Euro complete system that Trojan Horse used on their race bikes , really cool and $$$ http://www.youtube.com/watch?v=qaWqjkuNjlY&feature=related (Message edited by kdogshirow on November 21, 2010) | ||
| Albert666 |
wouldn't be very difficult, i've made reverso's for 1125's | ||
| Kdogshirow |
I have seen your work Albert666 and it is beautiful . Only problem is you are in the UK and I'm in California USA , lol . It would be cool to have one that would fit a stock header . What would you charge ? | ||
| Kdogshirow |
You know Albert666 , if you could make a reversa pipe that would fit a Jardine can , and a stock header , I bet you could sell alot of them , given the large number of Buell owners who have Jardine pipes . And I bet it would really make them run better . | ||
| Albert666 |
you have a message kdogshirow | ||
| D_adams |
This is the one I'm building now.  | ||
| N0ctrnlr3d |
D_adams, that is just bad@ss. The twin cans shown, are those connected to the 2-1 pipe right? Seems simple, I love it! | ||
| D_adams |
Yep, stays under the bike. I've brushed a couple of overly large speed bumps, but that's it so far. There's a guy at MMI there in AZ that has an RT-3, you'll hear him if he's around. (Message edited by d_adams on November 21, 2010) | ||

Looks trick D_adams !! Man , make something for us XB guys !  | ||
| D_adams |
You want something similar to that? Spread at the back, straight back, single oval, single round? I can do pretty much anything for the slip-on style once I get that xb12 here, assuming the mount points are the same for the xb9 and 12. Doing full headers, I could probably do it, but it would be a bit more expensive. I would need to get some dimensions or maybe even a 3d cad drawing of the flange. From there, it's just a matter of cutting and fitting some tubing. It's time consuming to do one-off fabrications like that, but they're fun to do sometimes. I know a few hundred machinists that could do the tooling for me and set up some jigs for that type of work. It would cost me a bit to set it all up initially, but would make it a lot easier to do them later. Unfortunately, I don't have a lot of space to store a lot of tooling in my garage, so I'll probably stick with doing the custom stuff one at a time for now. | ||

D_adams Funny you mention the RT-3. I attend MMI as well and hear the dude with it leaving every night. Never had a chance to chat with him. But I'll admit that I just stand there ears wide open taking in the sound. There's nothing better and I wish I had something similar. I like that the power pulse blows dust from the pavement as it rolls by. Because of that exhaust I was in search of something similar and not knowing until just now that it's yours. I shoulda known. I've searched for weeks looking for something like it online and found your site. On another note, when you mention you brush against rather large speed bumps. That could be somewhat of a concern, maybe not. I look forward to a finished product. I would like a setup without the chin fairing and have the cans right under the cracnkcase as previously mentioned. Without any idea of the shortened header and maybe possible loss of power, ever consider tuneable baffles. I could be talking out of my ass on that, but just a thought. When you get the bike in shop. Take a look at the area under the tranny. seems to have more clearance to the ground than right under the crankcase. What are your thoughts using that spot to create and or use the stock rear clamp area to hold the exiting cans sweeping outward or something along that |
