This used muffler assy fits:

2000-2007 XR650R

I removed this from my XR650R two weeks after purchasing the bike brand new

Very good condition with a couple very light scratches from being shuffled around in the shop 

If you rebuild or restore any type of machine you know how important it is to use genuine / original factory parts when possibe. A repair or restoration is intended to return that project to as close to original as possible, right down to the muffler.

If there's even a chance you'll need this/these replacement part(s) in the future you'd better get them NOW!. Keep this in mind,  replacement parts are always good to have. When you decide to sell your Honda, including a few extra replacement parts always sweetens the deal for both buyer and seller.
