wr450 pipe on a YZF

Hey all. Will a wr450 pipe fit a YZ450F? my buddy needs to quiet his bike down. let me know!

What year?

The '07-'08 WR muffler/midpipe assembly won't fit on the '08 YZ 450f header

If its an '06 or '07, it'll fit but you have to remove the gasket from the joint where the midpipe meets the header because the YZ don't have the small diameter header like the WR

the YZ is a 2007. What year pipes would fit that? Any or just the WR pipes from pre-08?

It would have to be a pipe from an '07 or '08 WR only.
