dude, I'm rocking the race exhaust with a Steeda intake, and my car is loud. Depends on what you are looking for. I am young, single, and like loud obnoxious things (granted the car sounds really nice actually). I wouldn't do headers and a cat delete as that would be stupid loud, but if you don't mind some noise save $50 and go race exhasut.
So yeah, the stealth exhasut still sounds mean and I assume much quieter at cruising speeds than mine. For the price, you can't go wrong with either FS Werks system as it looks great, sounds great and gives you 2.5 inch piping, which other systems can not boast.
