Sounds complicated, but it'* really simple. You have no resonator in a 93, so buy a high-flo catalytic converter (about 100 to 125 bucks), and the muffler of your choice. An F-body (camaro/firebird) muffler of either the Dynomax, Flowmaster, or Magnaflow variety. There'* only 2-5 horsepower difference between these three, so you have to mainly choose by the sound you want in the end. Some sound clips have been posted, but take it with a grain of salt....or rice.....some of the cars you'll hear ALSO have a resonator, or don't have a performance cat, or have aftermarket tips.....no 2 cars will sound exactly alike with the same muffler.
Choose wisely, my son.
