This valve improves throttle response and provides a bold exhaust note at full throttle, while remaining quiet at low speeds.
No modifications needed.
Hybrid Design: 50% recirculation, 50% atmosphere venting.
Tunable Piston: Adjustable for performance.
Bold Sound: Distinct blow-off noise at high boost.
Made from black anodized aluminum.
Includes installation guide and mounting kit.
