Our Active Valve version gives you the ability to tailor your sound to match the environment.
At lower engine speeds they can produce a wonderful deep tone, with volume and pitch increasing in direct proportion to rpm climaxing in a robust race car howl at the red line.
These systems have a Titanium silencer and thin-gauge Stainless Steel tube to achieve a combination of the lightest possible weight with strength and durability.
Active Valves - Designed for the everyday and long distance driver, can be refined or sporty when required to match your drive.
