The Active Tail Silencer (ATS) is the most effective way to lower sound output caused by a straight through racing exhaust system. The use of silencer has also been shown to actually increase mid-range torque in some vehicles. The ATS is equipped with an exhaust pressure sensitive spring-loaded valve that automatically opens and closes based on the point of exhaust pressure. This allows more exhaust flow under acceleration and high-rpm meanwhile maintaining lower sound levels at lower RPM.
