I would say yes.

A stock 450 muffler bolted right up to my 99 WR 400, no modifications required, and a White Bros pipe for a YZ 400 also slipped on with no mods.

I am now using the White Bros pipe from my 400 on my aluminum framed 07 450, only difference was the bolt near the rear shock didn’t line up. It’s been on for 2 months now with no problems.

thanks for that, i will get it bought :thumbsup:

+1 on that one. The q has a band for the can mount so you can adjust it to any slight differences in the subframe mounting points. Let us know how it fits.
