Can 03-05 WR450F's exhaust fit WR400/426F?

4 posts in this topic

Heya Peers.

I own an 00 WR400F and I would like to know if the steel frame WR450F's exhaust system can be fitted?

My country did not import any WR450F, so I hope you guys can advise if the header and end can point out the change and the difference in fitting.

Thanks!

an 03-06 WR450F stock muffler will fit

an 03-05 YZ450F stock muffler will fit with a tiny mod to the lower mount on the subframe.

Thanks guys! Totally appreciate your help!

I was worried if the header had a different bend/mount. Glad to know they are interchangeable!
