Does it fit

My bother is trading in his 400 for a 450 and he was wondering if he could use his fmf pipe(for the 400) on the 450?
Thanks,:)

i would say no but you could try, the mounts most likely will not line up but people make just about anything happen today.

you will need to to some tweaking, but anything will work if you have the desire for it to.

im pretty sure the muffler will but the head pipe is prob. diiffernt
