I had Fentons and 18" Porter steelpack mufflers on a '53 235, it was very loud and still the steelpacks took out the harshness of straight pipes. It sounded much like twin shotguns going off continuously, at least that's what the cop that wrote me up for too much noise said. Another cop said it was as loud as an airplane. I guess somehow cops don't seem to appreciate the finer things such as the sound of a very loud split exhaust on a straight 6.
