Hey all, I have a friend with a 2005 GT that wants to mod his car but wants to keep it quiet and stock looking. He only has a Zex and a Jlt and now talks about getting pulleys and LTs and I keep telling him to get an exhaust so that the car can breathe out with ease. He says he wants to keep it stock looking. So I figure I would help this fool out as he nevers uses this forum to talk.
