The HKS Silent Hi-Power Cat Back Exhaust is 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, increases both horsepower and torque numbers too. The Silent model is ideal for a conservative, yet aggressive exhaust tone that isn't too loud when compared to traditional aftermarket exhaust systems.
