If you save up and buy the Flowmaster Cat-Back I think you'll be plenty happy with that. After doing my mods(see below) I can squeel in 2nd gear easily! I notice people definately look when I romp on it in town! Just remember if you change the exhaust, you need to change the air delivery to get the full benifits of the performance. You'll also need to disconnect the battery, wait like 5 minutes and hook it all back up so the computer can reset and adjust to the increased air and vacuum. Drive it around town then take and open it up for abit and everything will be fine.
Hope that helps, happy mod'n!
