Close to completing a lot of restoration work on my 74 Challenger and over time several repairs occurred to my exhaust system as well as incorrect previous installation methods. What I want to locate is a high quality (and affordable) replacement exhaust system (want it to be 2 1/2 inch diameter)for my car. I want the system to include both mufflers and resonators for accuracy of installation, sound, and performance. My car has a 440/6 "X" pipe, and headers (TTI). Can a complete set up be ordered to facilitate installation and to limit welds? Do complete set-ups include hangars? Any advice and knowledge would be great.
