Performance exhaust for crf450
Can anyone tell me which system provides to biggest
performance gain, im looking for a tunable system which can have a spark arrester added for those pesky forrest rangers
sound decibles is not a concern w/me

Performance gain where? Down low? On top?

i would have to say on top due to bigbore kit & upgraded cam
which have totally increased my bottom.

have a look at the Big Gun pipes, top quality product with an interchangeable spark arrestor insert.
