I have an 04 GT and recently added a mac pro chamber and the new super 40 flows. My car just isnt that loud compared to my other buddies with new GT's. Should I switch out the flows with mac's or what ?
Have you ever let someone else drive your car while you stand on the street and watch? Try that and maybe youll change your mind. If not then get some bbk lt's with a bbk o/r h pipe and a magnapack cat back
