I love the way mine sounded with the stock mufflers and my O/R H pipe. I just hated the way they looked. I'm actually thinking about getting tips put on the stockers and painting the cans black and putting them back on.
Flowmasters sound great. I did some dyno testing and flowmasters lost power of the stockers and magnaflow made more power than most. I would get some magnapacks and be done with it.

sounds great! cant stop watching video.O/RH into m-80 mid mufflers into the new Pypes Bomb resonated tips. If you want to hear the sound of this click on my photography link and click on my car, the video will play.
