I want to stay stock in autocross so i might have my POP for sale sometime. To put a little spice back in my car i want some sort of free flowing exhaust. Most importantly is, What is dynoed to give the most POWER? Im willing to compromise on noise/and i prefer a sniper rifle tip over a melon launcher. Also, a nice audible non honda sound would be nice. Let me emphasize one more time, power is my biggest concern.
