So I bought this Warrior with the muffler in not-so-good condition. Of course I'm looking at an aftermarket pipe to help performance. I am considering the HMF sport, but figured I would ask here in case anyone has a spare laying around they would like to part with. I would prefer aftermarket, but it has to be quiet (relatively) and have a spark arrestor. The rest of the exhaust is ok, just the muffler needs replaced. Thanks.
