07 wr exhaust

Yes it will.

But if you mix/match headers and mufflers you will need to modify the sealing joint between them.

Actually I believe the diameter of the muffler inlet on the yz and wr are exactly the same. The yz has a larger diameter header and therefore uses a different size seal than the wr (outside dia of both seals are the same - inside dia larger on the yz ). I have an 07 wr and used stock header with shorty 08 yz muffler w/pmb insert - now have complete 08 yz system. works and sounds great.
