Hi TT members, I have this question about stock exhaust for the 98 WR400F. Will the stock exhausts from newer year WR models bolt on to the older 98 WR400F?? Did Yamaha upgrade or change the stock exhaust size or fittings at all??

Appreciate it if you can shed some light on this.

I know that the 1998-2000 exhausts are all the same for the WR400. I doubt that the exhaust off the 426 will work but I'm not entirley sure. Hope this helps you out. :)

Thks alot!! Appreciate it. I am thinking the 426s and 400s share the same mounting as well.
