This is the HKS Silent Hi-Power Cat-Back Exhaust System. This is a high-performance cat-back exhaust system designed with smooth bends, and a slightly larger increase in piping diameter to provide an unobstructed exit path for the exhaust gases. This improves the engine response, reduces turbo lag, and increases both horsepower and torque numbers. The Silent model is ideal for those of you who are looking for a conservative, yet aggressive exhaust tone that isn't too loud when compared to traditional aftermarket exhaust systems. It makes for an ideal choice for those who daily drive their cars but need to adhere to certain sound ordinances.
