All The Performance With The Noise! The Hybrid valve is back! In 1999, GFB's first Hybrid valve pioneered the dual port design, which was so successful the technology has since been adopted by most other brands.

As the car is driven harder, the valve opens further and more of the atmosphere venting port is exposed for a louder sound
