Im looking to order just the pipes for my 03 gt. It has a full exhaust with what looks like an x pipe but they dont connect. Basically straight pipes with a x bend. No cats. What is the magnapack part # everyone is running? The car has the stock muffler and sounds pretty good as is but I want it louder. Im going to have the stock muffler cut out and the magnapacks welded in, or maybe loudmouth 2s.
