you dont have dual exhaust, it just has 2 tail pipes. you have a y pipe from the manifolds, a single pipe from there on back, and 2 pipes after the muffler.
performance wise, x is probably better than a h pipe, but there is not a lot of room under the car for a lot of crazy pipes, most of the time, dual exhaust kills the ground clearance on 3rd or 4th gens.
