2004 aftermarket header?

I have a 2004 450 with the yosh trc slipon, was wondering if a head pipe would make any difference in power? I searched and I guess I suck at that. thanks in advance.

it would make "some" new power but the 03-06 wr came with a yz header so your already flowing pretty well. if it was me, i would look in to cams or something before i spent money on a header for an 03-06 wr. :lol:

that is what I thought, thanks, have any cams lying around?

no but all you need is the 03-05 YZ 450 exhaust cam...the intake is the same as the YZ:thumbsup:

no to mention its only like 125 bucks...cheap and easy mod :lol:
