great choice, and also go with stainless, catbacks/ x pipe - ran that set up on my last car, an 01 modified GT, fine sound and good performance.
your other option...install electic exhaust cutouts after the cats, dump the exhaust before the mufflers....they operate from inside the car, flick of the switch flowthrough and loud, flick of the switch legal....ck out
-you tube- lots of exhaust cutouts clips there.
here is what they look like
