It isn't exactly Portland or Vancouver, but the "Muffler Man" in Centralia, WA does excellent work. He did my 67 and I am proud of it. 2 1/2" aluminized pipe with crossover pipe, everything solidly mounted and routed beautifully. Exits just where the factory exited the SS cars. I supplied the Flowmasters myself and he had no problem with it. He is also a fellow gearhead and a good guy. Best part, he is very reasonable in terms of price. Check him out.
