426 pipe on a 400?

Anybody know if a 2002 WR 426 stock exhaust can be used on a '99/'00 WR 400, to make life easier in cleaning / changing the oil filter screen.


yep as far as i know

Yep it works great. I've got an 02 YZ header and silencer on my 99 WR. I can honestly say it works better than any other exhaust system I've seen.

Ok, who out there has one for sale? I am looking for one. Thanks, Ron S
