The Apexi PS Revolution exhaust system is the first of a new breed of exhaust systems that offer very high flow and maintain a legal exhaust note under normal driving conditions.

The Apexi PS Revolution utilises a retracting valve that is activated based upon the exhaust pressure exiting the system. Under high throttle or high load situations the valve fully opens to enable full exhaust flow and maximum power. Apexi exhaust systems all utilise high quality SUS304 stainless steel and full mandrel bent piping for superior exhaust flow, strength and minimum weight.
