One of the must things to do is add an aftermarket exhaust to your Ford Mustang. It is crucial to make your Mustang as free flowing as possible and give it a little growl. Mustang is one of the best sounding muscle cars ever made, so you might want to get a nice catback exhaust. List of exhausts come from companies such as BBK, Borla, Bassani, Flowmaster, Magnaflow, and SLP. I'm kind of partial to flowmaster exhaust because of the sound, but it's not a very good free flowing catback. I've heard Bassani is a great free flowing catback exhaust, along with Magnaflow.
