I recently had Stainless Works 1-3/4" headers and a catted y-pipe installed on my '07 TBSS. Other mods done to the truck include a Magnaflow catback, IEATSRT8 cai, and a tune. I was looking for an exhaust setup that was a little more refined since this is my daily driver and I already have a car that makes loud racecar noises. It's still whisper quiet when cruising but has a great mellow tone and really comes to life when I mash the gas. The vid really doesn't do justice for the way it sounds. It's louder in person, but we used a crappy camera and my GF isn't the best at taking vids. http://www.youtube.com/watch?v=2rN1iDvIwvA
