Hello all, first post on this board.
I removed the muffler on my GT and left the resonator on. Had straight pipe put in place of the BIG muffler and a nicer tip that fills up the semi circle cutout in the rear bumper. It sounds great, not that loud but much deeper. The car SEEMS faster, but I can't really swear that it is. I think it just gives a better overall feel when you can hear a little grunt from the engine.
