hey guys, i did lots of searching on the magnaflow exhaust and i haven't really find anything on it. most people have the custom muffler but i am very curious about the axle back system for the gts. does anyone have one and tell me how it sounds and the gains?. unforunately, the magnaflow website doesnt have the sound clip on the celica but they do for other cars. is it because the magnaflow axle back is not popular on our cars?
