hEY EVERYONE! LOOKING FOR GOOD INPUT ON THE FLOWMASTER AMERICAN THUNDER CAT BACK DUAL EXHAUST SYSTEM. IT HAS A 3' INPUT WITH A 4' CHAMBER LEADING TO 2 2.5" OUTLETS. IS THERE SOMETHING ELSE I SHOULD CONSIDER TO COMPLIMENT SUCH A SET-UP? I HAVE NO OTHER PERFORMANCE MODS TO DATE, JUST SOME COSMETICS IS ALL.
