I am selling this Powertech canister style muffler with removable silencer (silencer is painted flat black) for $50. The tip is just under 4". Muffler is in good condition, a few scrapes on the bottom. The muffler has an adjustable plate for customizing the sound but it didn't make much of a difference so I just welded it on to the silencer. So there are no bolts on the silencer like in the pic.
