03yz 450f muffler will work in 00yz426 4stock

Can any one tell me if 2003 Yamaha YZ 450f stock muffler will fit a 2000 yz 426 four stroke?

I believe the only difference is the mount. If you grind off the mount and make a sliding clamp style mount you should be able to get it to work.

How about a slip on 450 exhaust on a 2001 426??

like I said dude, the mounts are different and will require some fabrication.

thanks for the info :)

a welder and steady hand will fix anything

All it needs it the mount grounded out..Trust me been there
