A friend of minetold me that the exhaust on the f2's and f3'sare interchangable with the f1's. i was wondering if anyone knew if that was true. thanks

 

the mufflers MAYBE, but I very highly doubt the headers are. the motors alone are completely different, and when I look at pictures of each, the headers look totally different too.

 

i agree with hurricane rider. you can use pretty much any muffler as long as you can get it to fit. as far as I know theres not really an issue with back preasure unless your using a smaller diameter can like something off say smaller than a 400cc bike. (correct me anyone if thats wrong) headers... different story, not so much cos of pressure but because they just wont fit at all! start fabbing your own and you run into problems of creating back pressure in the bends. I'll be fabbing an underseat pipe on mine when i get that far (streetfighter) using the stock headers.

 

all mufflers have there own unique backpressure. thats why the companies make different styles. otherwise every company would make only one can.

 

Detroit Cane has a good point. You should really try and stick with the type of muffler ideal for you bike. As for the headers; there is no chance that they can be compatible.

 

i know the headers are different they changed with the design of the motor i was just wondering if a slip on from like an f3 would work.

thanks

 

it will work, I have friends that have taken cans off of different brand bikes and swaped them out and they work. The catch is you have to figure out a way to tune the bike so that you get the most out of the exhaust. If u use a can thats not made for your bike then your kinda on your own as far as tuning because no company makes instructions for tuning an exhaust for a 93 when put on an 89.

 

so if you use a race can which is free flowing what back pressure is there???

 

they are free flowing but still restrictive to a degree. all cans have chambers in them that create back pressure, the back pressue is determined in the style of chambers and the amount of packing used. just because u can see straight through it doesnt mean it has no chambers. any and all engines rely on some type of back pressure from the exhaust system to help produce power. For instance, ride a bike with the can on and then ride it with the can off, you will be able to tell the power difference no mater what type can, stock or aftermarket.

 

intresting! im gonna play with a few cans now and see what results i get as i jus got my new welder! I'll run with no can too jus for giggles and to see how big a difference it makes.
