hey, i finally got an exhaust system put on. the mufflers are like flowmaster but i think flopro makes them. they are called force and they sound really nice with an O/R x pipe. i got long tubes into a bassani x and out 3 inch tails after the mufflers. sound mean with the f cam and thumper heads and when cruising i can hear myself talk and not annoying. acceleration sounds really badass too. you should try the mufflers at 30 bucks each from summit.
