Of these two, which one has the deeper more aggressive tone? I have not been able to decide between them.wykdrt said:Flowmasters new super 40 sounds pretty good. Its not obnoxously raspy like the original 40. It has the same loudness but it is a deeper sound than a raspy sound. My buddy has a 4.7 with gibson dual sport on it and it sounds pretty good. Quiet at idle but when he gets on it it sounds pretty good.
