09 450 exhaust question

3 posts in this topic

i have the GYTR full system on my 09 450 and I noticed the stock header is bigger than the one that came with the system and I was wondering if I could make more power with factory header and jet recommendations for 700ft elevation with 3x3 air box mod

Thanks

:p

P.S. sorry for all the run on sentences i failed english in highschool

The stock header is large to compensate for the plugged up stock silencer, it wont give you any hp gains. Size isnt everything btw, its all about a happy medium between moving enough air(large diameter) at a fast enough speed(small diameter).
