Furious Posted April 2, 2007 Share Posted April 2, 2007 I'll sum up.. I'm trying to build a super light, MotoGP style exhaust system. I have the header from a Two-Bros shotgun system. I'm interested in using this 240mm can from Micron I'm going to need X amount (5-8") of mid-pipe to get past the peg. The can weights 1.5 lbs. With it being this light, am I going to have to anchor the can somewhere other than the pipe? Any other thoughts? Quote Link to comment Share on other sites More sharing options...
devilisht2003 Posted April 2, 2007 Share Posted April 2, 2007 my hindle is a short can, there are pic in my gallery i think Quote Link to comment Share on other sites More sharing options...
Furious Posted April 2, 2007 Author Share Posted April 2, 2007 my hindle is a short can, there are pic in my gallery i think I didn't see one in your gallery. Nice pic of the X-11 though. Quote Link to comment Share on other sites More sharing options...
devilisht2003 Posted April 2, 2007 Share Posted April 2, 2007 i'll find a pic, its not a X-11 is a photoshopped XX i was thinking about doin edit: Quote Link to comment Share on other sites More sharing options...

Furious Posted April 3, 2007 Author Share Posted April 3, 2007 Too short? Jeff, did you see any HP gain with that setup? Was it the stock header? Wanna build me one? i'll find a pic, its not a X-11 is a photoshopped XX i was thinking about doin edit: That's about what I'm going for. Do you have any problems with your foot over the exhaust can?

devilisht2003 Posted April 3, 2007 Share Posted April 3, 2007 no problems sounds/looks good. i did paint it black which i like better. Quote Link to comment Share on other sites More sharing options...
Byrdman Posted April 3, 2007 Share Posted April 3, 2007 Jeff, did you see any HP gain with that setup? Was it the stock header? Wanna build me one? That bike was carbureted and I didn't have the system on long enough to bother to rejet the bike. I would assume a slight HP increase could be gained but at the cost of unreal sound levels, I don't know if it would be worth it? Quote Link to comment Share on other sites More sharing options...

Probably pretty cool for the first 10 minutes or so. Quote Link to comment Share on other sites More sharing options...

Did you have someone bend a mid-pipe for you or did it just fit right? Where did you attach the can? Quote Link to comment Share on other sites More sharing options...
devilisht2003 Posted April 3, 2007 Share Posted April 3, 2007 muzzy 4-1 header fit 2 size adapters from advance auto parts and can is forced on enough to just stay Quote Link to comment Share on other sites More sharing options...

That is ultimately the type of system that I would want in terms of center of gravity, but I don't think I would like THAT much noise coming out of the bike. Still, I'm tempted.

xrdracer Posted April 6, 2007 Share Posted April 6, 2007 I for one do not recommend changing exhaust system pipe dimensions. To have the proper scavenging effects to pull the exhaust out of the head and the proper back pressure etc. takes alot of R&D. Any changing of these dims will result in less power produced. It may sound "better" and give the impression of more power, but in reality it will produce less power. Quote Link to comment Share on other sites More sharing options...

Mass centralization = better handling. I for one do not recommend changing exhaust system pipe dimensions.

It may sound "better" and give the impression of more power, but in reality it will produce less power. Well, I am working under the assumption that by using a header designed for the Bird (admittedly the 97-98 and I have an 03) that there won't be any power lost. If there is any loss after the bike is tuned on the dyno then I'm hoping it'll be made up for in the weight savings. Quote Link to comment Share on other sites More sharing options...
BDAZ XX Posted April 6, 2007 Share Posted April 6, 2007 How much do you honestly think you are going to save going to a shorty muffler vs a normal aftermarket pipe?? Minimal weight savings and power loss vs a good Ti aftermarket pipe. If your going for power and weight savings get a full Ti Akro or something similar and stop dicking around with a modded, heavy, stainless system. By simply adding a shorter mid and muffler I would venture to bet that you will loose power and its still a heavy system due to the stock header pipe. If its all for looks then mo powwa to ya!

I'm not using the stock header. I have a 4-1 header from a Two-Bros Shotgun system that I'm going to use. I would imagine I'm going to save half the weight of an after market system since (mid-pipe back) the mid-pipe will be half he length, as will the exhaust can. I guess I won't know for sure till I try. Quote Link to comment Share on other sites More sharing options...
Byrdman Posted April 7, 2007 Share Posted April 7, 2007 I guess I won't know for sure till I try. Go ahead and play with it, we need more creativity around here. You can always go back to stock or aftermarket. Quote Link to comment Share on other sites More sharing options...

I guess I won't know for sure till I try. My TiForce complete system is one of the only fully titanium system systems available for the XX and weights just under 9lbs including can, not to mention will make the most power. The Akra has a stainless steel header, weighs only 2lbs more (IIRC), and is very close in performance to the TiForce. Compare those weights to just the weight & performance of your 2Bros header. Now, if it's just for looks, that's something else. Quote Link to comment Share on other sites More sharing options...
cbrxxquad Posted April 7, 2007 Share Posted April 7, 2007 ebay Kerker makes a tuneable shorty that I have seen that would work. This is an example, but not the one I am thinking about. Will se if I can find the one, but I think the one I was looking for was discontinued that would fit. cf Quote Link to comment Share on other sites More sharing options...
