I Have a 2002 GT with a 5 speed. I am looking to change the midpipe setup. It has the stock h-pipe. I want to either put on a o/r h-pipe or a o/r prochamber. I have a stock cat back with two cherry bomb glass packs. I enjoy the sound but i would make it louder while keeping the same kind of tone. I like a deep rumble instead of a metallic sound. thanks
