What is the Sound Architect™?
Our Active Valve version gives you the ability to taylor 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.
Active Valves - Designed for the everyday and long distance driver, can be refined or sporty when required to match your drive.
As shown in the video we also supply GPF delete pipes #AU455A which are a bolt on direct replacement part and offer the optimum driving experience.
