want to wake your car up swap the ring and pinion to either a 3.73 or 4.10 ...bunch of exhaust systems out there to choose from - you want to keep your car street legal ...keep the cats and just get a cat back exhaust system - if not i'd lose the cats and go with an off road h or x pipe ...h for sound x for performance - if you want flowmasters id go with either a delta or super 40 ...the originals drone way too much after a while, delta is the quietest of the 3 while super 40 is somewhere inbetween

i really wouldnt waste my time with bolt ons - the gears/exhaust should be your first mods although this is just my opinion other people may have another say in the matter

good luck with the stang
