Define "better-sounding". That annoying BBRRRRRRAAAAAAAAPPPPP sound of a set of open-chambered mufflers on an inline six makes me want to get out my 12 gauge pump shotgun and a bunch of 3" magnum turkey shells! "Smittys" used to refer to steel-pack mufflers with steel wool instead of fiberglass in them, not too sure whether that's the case now. That sound is almost as annoying as a rice rocket with a tiny 4 cylinder and a f#*t can "muffler" on it.
