Due to rust I need to replace my exhaust system. I do not need anything really much different from stock. Might only replace from the split back. Possibly a deeper sound but not noisy. Do I need to replace both the resonater and muffler? Is there a shop in the Portland, OR area that anyone recommends that could do a good job and give me some advice? Stock 1972 car.
