Big Block muffler choice

18” resonators after the mufflers on each pipe. You can use small, straight through mufflers as resonators if you like. Then get some resonated tips.

This is exactly why I am running 2.5” duals on the 383 Swinger. I don’t want obnoxious, and I don’t want drone. The smaller pipe will make less noise, and less power depending on your combo. The small power loss from the 2.5” pipe and the extra mufflers will be worth the final exhaust tone. IMO, of course.
