Chatty,
I know there are plenty of decent exhast shops in "the Vegas" (I'm oridinally from Cleveland). Hit up L8 Apexing aussie for a couple of Magnaflows, or run a bassani style exhaust with the muffler(maganflow, dynomax you choice) where the resonator is, and then just a couple of small resonators after the "Y" split or some quality resonated tips.
