I am ready to buy the Roush axle back exhaust, but I have a buddy with an 02 GT with a MAC system that just sounds amazing! I was wondering if it's possible to mate the two together? I am planning on getting the MAC long tube headers and cat-back exhaust. Also, would it be worth it to get rid of the Cat's? Kind of new at this and am up for all sugestions. By the way, it's an 05 GT Premium.

Thanks!!
