Hi guys - I think I know the answer to this question but here goes.

I've got a 05 WR450f and I like to put a yoshimura rs3 slip-on on it.
problem is they only list it for a 03-05 yz450.

I would think it would fit since I've seen many posts about installing the stock yz pipe on a wr, but I just want to make sure. :applause:

Yep! it will fit. Exactly the same. Good choice with the yosh, they seem to go nice!

I don't think I have ever seen a WR specific muffler made?

be prepared for some serious noise though,it came with a removable spark arrestor.

It doesn't seem that loud! well yeah, I wouldn't ride it around the neighbourhood!

The reason I'm getting the Yoshimura rs-3 is for a little more power, but also the noise level, I went from the bone stock exhaust on my ttr250 to the rs-3
and it wasn't that much louder the the stocker. My 05 WR has the normal restricter removed, and I plan on running the new pipe with the spark arrester. so I can't imagine it being much loader then that.
