i was wondering if i would buy the apexi GT Spec Muffler cat back exhaust for an acura gsr , would it all line up as the same as mine right now.. i have the greddy evo2 cat back exhaust... would the piping go in the same direction and all the curves? the motor that was in the car before was a d15b7.. and the model of my car is a 93 civic dx.. does anyone know?? thanks
