Apexi 90mm ATS (Active Tail Silencer)
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.
