Has it got the stock muffler on it or an aftermarket one on it?

I would definately start with a muffler repack, when was the last time it had one?

If you have a stock WR pipe, it is not rebuildable. You have some choices on making it quieter using a muffler insert. Yamaha GYTR sells one, but it usually falls apart. Promoto billet used to make one, but I heard they don't sell it anymore. That leaves the Quietip from quiet products( and one other (maybe vortip?) to choose from. Good news is that the stock pipe has a spark arrestor already.
