yz 450 exhaust fit wr400??

Would someone be able to tell me if a yz450 muffler will fit a 99 wr400. Have access to a cheap one and would be good to fit even if I have to do a few mods. Thanks

Have I stumped the guru's or is this a stupid question?

If it's an 05' or older probably. I can only assume the new aluminum frame on the 06' YZ would have different bend and mounting.

I took my stock exhaust off of my 04' 450 and mounted it on my 400 with little trouble, I just had to hog out the rear mounting hole a little bit :thumbsup:
