mustangs, unlike f-bods, pretty much sound good no matter what exhaust you go with, when I had my '03 GT I had BBk lt's, shorty orx, and an MRT catback with v-force mufflers and it was honestly the best sounding car I have ever heard(go to www.mustangracing.com), I miss the sound but yah check out their catbacks they are greay quality and not many ppl have them....

My 96 is LOUD!! Shorty FMS headers. Offroad Hpipe, SLP loudmouth. Its really loud

Ok I switched from the standard LT's, O/R H, and flowmaster dumped to LT, O/R H and dynomax race bullets dumped. OMFG! The filling in my tooth rattles it's that damn loud. When I go WOT baby Jesus cries!!!!!!!!!!!!!!!! This has to be the loudest exhaust eva. ;) -Mark

i would recomend Str8 pipe, but i have flow off road-xpipe and its pritty load... but my buddy has a 03 gt with borla and it sounds like a stock cobra, but my other buddy has a 94gt with str8 pipe and its the meanest mustang ive heard with out it being tubbed out~!
