If you have a 93, as your screenname suggests, a 2.25" pulley is the recommended size to get a good increase in boost without causing a lot of knock retard. To better feel the benefits of the increased boost, I'd suggest a CAI (you'll have to make your own, search rice pipe), and a high flow catalytic convertor (I've got a Magnaflow, and I like it). As far as mufflers go, I have a 2.5" in/2.5" dual out F-body Magnaflow and I love the sound.
