The big offender with a 2 chamber Flowmaster is the resonance, especially from the 40 series. Add performance goodies, especially a lumpy cam, and it'll get really nasty inside at cruising speed. Go with a Delta Flow 3 chamber 40 or a straight flowing muffler like the Walker Dynomax mufflers if you want your car quiet enough to listen to your system at reasonable levels. Or be prepared to shell out on generous amounts of sound deadening. The new Super 40s are really deep sounding and are supposed to be quieter inside than the originals. They aren't quite as throaty and aggressive as the original 40s, though.
