RE: TT Pro 40 Muffler GASKETS...source?
Well...these are certainly readily available, cheap, and easy enough to make so they could be replaced at every muffler removal. Still, I'd love to have METAL GASKETS ala Nelson and Jett.
Question for you guys that don't use gaskets: Do you lap each mating surface on a dead flat board with 400/600 grit paper attached?
