Description:
The ATS was developed as a high performance evolution to the standard tail pipe silencers available in the market today. While many people enjoy the power gains of a racing exhaust on the track, often times these systems require a silencer to be installed in the tip for use on the street. While sound output can be dramatically lowered using a non-adjustable silencer, unfortunately response and power tend to suffer due to increased exhaust gas restriction. The ATS (Active Tail Silencer) uses the same active valve technology as the PS Revolution exhaust system. The spring loaded valve is engaged and disengaged based upon exhaust gas pressure. This allows for effective sound suppression for the street, without the power loss under high load. Dyno tests have proven power levels to be nearly identical to an exhaust using no silencer at all.
Please note that, due to the tapered tip of the N1 Evolution exhaust system the ATS Silencer WILL NOT fit properly. This is only true for the N1 EVOLUTION mufflers, all other exhaust systems will fit without problems.

Q: What is a muffler? Are there different types of mufflers?
A: According to our resident expert Deryl Atanasu, Mufflers are positioned by the manufacturer where there is space on the car. All mufflers tend to be placed behind the rear axle, as this allows a lower floor-pan in the passenger compartment. Vehicles with single exaust generally have the muffler placed in a direct line with the tailpipe and just before the exaust tip. Some high-performance vehicles have a dual exaust (i.e. corvettes), where both left and right sides have a muffler in a direct line with the tailpipe and just before the exaust tip. Other vehicles (i.e. camaro, firebird) have a single exaust pipe going back just past the rear axle. It then enters a muffler that is mounted in a side to side position. From there two tailpipes exit the muffler and extend to the rear or out the side of the vehicle behind the rear axle.
