RE: pitts muffler fix
Mountain, I am using JB weld on one now that seems to be holding up ok for now. If I were you I would use a dremel and skuff up the area around the weld and clean thoroughly and use the JB Weld. Use some acetone to clean the area thouroughly to get the oil off or the JB will not hold at all. The cost some of these welding shops charge would make it almost as cheap to just buy another one new.
