I have 04 GT and for *****s and giggles am thinking about taking off my h-pipe. I am going to leave on mufflers and tips cause im going to put it back on, but since it will be dumping right out of the manifold, how will it sound? Will it help or hurt performance? sound be horrible? Im just doing this for the hell of it, just for a day or two, cause i'll be getting x pipe here soon, any suggestions on brands? Bassani?
