I was wondering if I bought a FMF 4.1 pipe with a header for a YZ 450, would it fit on a WR 450.

I'm almost positive the headers are the same, but not the canisters.

It depends on the year. I think the YZ got the aluminum frame a year or two before the WR, and I think the exhausts are not interchangeable for the year(s) that the YZ is aluminum and the WR is steel. Maybe someone can back me up on this.

Ya sometimes the WR is a year behind the YZ. So a 05 yz450 might also might be compaitable with a 06 WR450
