Just returned from the Krause Auto Auction and Car Show in Auburn IN. While I was there I met the Waldron's from Michigan. They advertise exhaust systems in the Bugle. I went ahead and ordered the stainless steel dual exhaust system for my '63 Electra, but I have some questions before he begins working on it. -First, I hope I'll be happy with his work. Any comments? -Where should the pipes "correctly" terminate? From the rear of the car, or behind the wheels? -Were the original pipes camphered, or squared off? -My parts manual lists two different mufflers for my Electra. Under section 3.701 they are... 4400-4800 (dual) muffler 1355436, and 4400-4800 (dual) Sport Car Exh 1357150. Since my car is a convertible with bucket seats, I'm thinking the sport car muffler would be correct. What's the difference between the two mufflers? Thanks Pat
