Havent posted up anything bout my bike over here in a while, so I figured I'd share this. I cut up two cherry bombs, cut my header down and then heated it up and bent it how I needed it positioned, then welded the shortened cherry bombs in place. Turned it on, and it was LOOOOUUUUDDDDD! So I bought some baffles that are used in race cars with open headers or straight pipes to reduce noise so they meet noise regulations. I welded those in and it sounds awesome now. I just gotta get 1 new header bolt so that I can tighten the header down so it stops leaking, then I'll get a sound clip for ya'll.

Anyways, heres the goods:

the header(s) after being cut:

this is the bracket I cut that normally would hold the left and right sides togeather:

this is the section of the header I cut off:

my new exhausts:

here they are next to the sections I removed:

I was pretty proud of myself at how nice my welding was since I hadnt touched an oxy/acetylene torch in almost 2 years, and since my MIG welds I did on the subframe all looked like ass.

more pics (stupid image limit, lol)
One side freshly welded:


Other side:


On the bike:

the block of wood was what I used to get it to sit vertically so I could line em up and make sure they were even height and whatnot.

Other side of the bike:


Baffles in the exhaust:


I decided to weld all the way around (instead of just tacking it in) so that it would be sealed and the exhaust couldnt escape around the baffle. This was a bitch to weld since being inside the pipe the flames would hit the baffle and kind of reflect back out and it burnt the crap out of my left hand (I ended up wearing 2 pairs of gloves, and one caught on fire, lol). At least I never have to worry about it falling off!:


What do ya think? It looks sweet when you look at it in person.
The kickstand does hit the pipe, but it goes far enough up that it locks in position, so it shouldnt be a problem. I can always get a skinner spring for it and that should solve the problem too.

And yes, the chain needs tightened. It was tightened to the correct slack, but its brand new, and just the 20 minute ride up to school seems to have stretched it a bit. Either that or my wheel moved forward (which wouldnt be good, lol)

Oh, and it will be all painted black. I know, the red with the burnt part and flash rust looks soooooo awesome, but alas, black it will be.

It was way too loud for my taste with just the cherry bombs and i would imagine straight pipe would have been even louder. I mean, with just the cherry bombs it would have drown out most harleys and choppers, just for an idea how loud it was.

Wow, most people usually have something negative to said about homemade exhausts, but that is fricken sweet! Hats off ta ya for being different. I always thought Buell-style exhaust to be the smarter way to go - less weight, lower center of gravity, and makes the ass of the bike cleaner. Good job!

looks good man.
the only concern i would have with that is the exhaust coming out so close to the rear tire... and possibly melting the tire while standing at a red light? but then again, i dont know what im talking about; just the first thing that came to mind.
looks really nice though, cant wait to see it in all black.

errrrrr, creative anyway. honestly i don't know what my reaction is. I guess I'll have to wait and see the bike with the body work remounted and some more pics. I will definately give you props for creativity....

i'd like to know what the bike does on a dyno now too.

Thanks guys.

Yeah, its pretty loud. Its a little louder than a D&D I think, but its not really earsplitting or obnoxiously loud. I like it - its mean as hell, real deep - somewhere between a bad ass ducati, a sportbike, and a muscle car (its really hard to describe, lol). I can always add some fiberglass packing inside the baffle if I really want to quiet it down more. Just would have to pack it in there, then tack on a screen at the end - real easy.

As far as the tire getting too hot, thats a realistic concern, no doubt, but the way they are angled, they should blow out on either side of the tire, so if anything it will just serve to heat up the sidewalls - which really I would think would be a good thing. Who needs chickenhawks, right? lol. If I ever do start seeing some meltage, or notice it getting too hot, I can always just buy some 90 degree pipe pieces from autozone and cut off the straight exit pipe and weld in those to point it off to the side or down or something.

Tuna, the overflow actually mounts up inside the subframe, I just knocked it out of place when I was working. I actually chopped the battery box as small as I could and then moved it as far forward as I could - it sits about half under the tank and half under the seat. Then I mounted the cooland bottle right behind it, up inside the subframe. And I mounted my reg/rec, rear brake reservoir, ecu, and fuel cut off relay all inside the subframe. The wiring runs so that it is all hidden inside the frame and subframe, so when it is complete, I'll have a completely smooth undertail (kinda like the new r6) and all that stuff will be completely hidden from sight. NO coolant bottle, no brake reservoir, no wiring, nothing will be visible when its done. And I tucked all the wires up in the frame as much as possible so the motor looks pretty clean from the side, and you really cant see hardly any wiring from the outside, except stuff that runs to the motor (cant do nothing about that, lol)

Sodamninsane, the other thing I thought of when I was contemplating how I was gonna do this was using the little 2 stroke racing mufflers. They are really small diameter, and would work well I think. Of course, it'd still be loud as hell, but seriously, you dont even wanna know how loud straight pipes are. Think of the loudest chopper you ever heard, then double that for the 4 cylinders v. 2 and you can get an idea.
The reason I didnt go with them is cause these were only $17 a piece, and becasue the 2-stroke cans usually have a small (less than 2") intake pipe, so you would have to cut that out and widen the hole and then weld in a 2" pipe. It woudnt be hard, but for the price this was the best option I decided.

I'll get a sound clip once i get the new bolt to take care of the header leak. I should probably buy new gaskets as well - which sucks cause I just bought those like a month ago :jerkit: .

wow, i'm really on the fence about this also. The idea is definitely awsome and it was a cool project regardless. With what you have now i would definitely put some angled tips that shoot it down and out. Would like to see how it looks with bodywork on also.

*oh yeah...how come in the pictures the tail section looks like its 42 feet above the rear tire?

I dunno, good question apbt. I think its just the angle of the pics mostly. I mean, there is a lot of clearance, but its really not that high. In the pic it looks like one of those euro fighters (not my taste, but whatever) and it doesnt look anything like that in real life. I'll get better pics when I do the sound clip.

Bodywork's probably got a month or two left on it. I got the two sides layed, and I just glued the molds togeather for the upper. So tonight I'm gonna go sand the upper and get it taped up and prepped for glassing, then if I feel up to it I'll glass it tonight, and if not I'll lay it up early tomorrow morning. Then when thats drying I'm probably gonna sandblast and paint the exhaust, and maybe I'll start trimming my two side body pieces and get em off the molds. Once they are all off the molds, I still gotta cut em and fit em and glass em togeather, fab up some body mounts, cut them into two pieces (upper/mids and lower) and do all the bodywork. I also still gotta make an undertail and subframe covers, which I havent started yet. Those wont take long, but its something that needs done before I can paint it. I decided I'm gonna pay someone to paint it, cause as much as I would like to do it myself, I really want it to turn out showstopping nice. So I figure the paint is a touchy deal so I'm gonna let a pro do it.

PRE-HEAT!.. not such a bad idea,,,, Just never stop at lights or stop signs.

Yeah...

I'm gonna have to see a pic with everything put back on...

If you want an exhaust like this so bad, buy an R6 or new gsxr
