1993 Mazda RX-7 (FD3S) HKS Hi-Power Exhaust

While shopping for an aftermarket cat-back exhaust system for my FD, I had a hard time deciding. My main struggle was finding good video or audio clips of different set-ups on my vehicle to help me decide before purchasing. My intention is to help others that may be in a similar situation as I was a few months back.
