There are a ton of these threads, but I once was in your position, so here it goes. You want that "classic" muscle rumble, Flowmasters American Thunder Catback. I had that, but then switched to SLP LM 1. Different sounding, LOUD, I sometimes miss my Flow's, but not that 2k drone. Do a search, ton of threads, vid, and sound clips. SLP is also all SS, and about $360 shipped
