haha before i rolled my gtp and still now i guess (yea still drive it) i took a hack saw jacked up my rear(rims still on) and cut the muffs off right where it bends. This was done at 2 in the morning, took it out for a drive and im suprised no cops showed up. in the morning i went to advanced bought 2 2" exhaust pipes and 2 clamps and clamped them on there. It doesnt look so pretty but it sounds great at 2k and i dont regret it.
