well in my neighborhood there is a kid that has an 02gt. His car sounds AMAZING. i asked him what he had done to it, and he claims he just has intake and exhaust. his car is lowered, and he told me b4 he has full magnaflow exhaust, minus any cats or mufflers. I know a lil bout cars, but im sure that theres no way his car runs 11.91's(which is written on his quarter window as well as the track numbers or whatever they are written on his windshield) with just an intake and exhaust, and lowering springs, is it?
