Working on my '63 and I just noticed that the Flowmaster mufflers were installed backwards. The big word INLET is stamped on the back of mine. The previous owner had them installed. I would have noticed before it left the muffler shop. My question is: Is this going to affect the performance of the engine any? Should I yake it and have them turned around? I'm going to have to carry it anyway and have the tail pipes moved so I can bolt up a receiver hitch.
