I have a full stainless exhaust system minus the mufflers for my 63 R1. I bought the system from Don Simmons back in 1990. Can't remember if he had the name Silvertone back then. At the time he only had one muffler and wasn't going to be getting anymore. Needless to say, I never put the system on the car, until now that I'm putting it back together. Somewhere along the way he got a new manufacturer. Any recommendations on mufflers. Anybody use Silvertone mufflers. He has 3 different ones.
