09 YZF Exhaust fited to a 09 WR

Will 09 450 YZF exhaust system bolt up to a 09 WR450?

No problem. All aluminum frame YZ exhausts will fit all aluminum frame WR's.

I assume you mean complete system as the headers are a different size. You can still do it but you would need a gasket between the smaller WR header and the YZ can.

ok great, now if jetting is needed would you expect to go larger on the main or smaller?


Slightly larger if at all.
