- Current tail silencers are a restriction for power under high load and the user sacrifices power for quieter sound.

- The ATS allows for quiet sound during low load, but under high load, the pressure activated valve opens wide up
for straight through power!!

- The ATS eliminates the need to constantly install or remove the tail silencer.

- The ATS (Active Tail Silencer) comes in 115mm and 90mm sizes for most exhaust system applications.

- APEX Exclusive Design

- No need to change exhaust systems! Any A'PEX muffler can become a variable sound system!
