O.K. great progres has been made on the car with a focused effort this weekend. Pictures to follow. I need to buy a muffler for the exhaust system. I can get a good deal on a 2.25" x 4.5" x 10" long unit. My question is...is this too short to make the required sound levels? What are other guys running successfully? Obviously, I don't want to buy something that I will have to replace after the first outing. TIA.
