need information about the mac cat back exhaust system for the lightning , compared to flowmaster & megaflow systems. im looking for some hp increase without excessive noise at full throttle.
i have heard the mac cat back system & it sounds real good, but do any of you all folks have quarter mile times vs other cat back systems to compare with.
i have heard the new flowmaster system is very loud.
i have heard the megaflow system is nothing but a straight through glasspack-steelpack system.
any help from someone who has installed these systems would be appreciated. v/r william ambler
