MACH 2: The Ultimate 100% Recirculating Diverter Valve

Faster Boost Recovery, Maximum Reliability, Zero Noise

If you want performance without the attention-grabbing sound, the GFB Mach 2 is your go-to upgrade. Designed for turbo enthusiasts who value stealthy power, this valve delivers quicker boost response and rock-solid reliability.

Why Choose the Mach 2?

• Boost Recovery Up to 30% Faster – GFB’s TMS technology helps you get back to peak boost faster than a stock valve.
• 100% Recirculating – Keeps your turbo setup as quiet as stock while maximizing performance.
• Direct Bolt-On Replacement – No modifications needed. Just swap out your factory valve, and you’re good to go.
• Unlimited Boost Holding – Unlike factory valves that leak under high boost, the Mach 2’s pressure-balanced design ensures zero loss of power.
• Smoother Throttle Response – Say goodbye to lag and enjoy instant power delivery.

The Problem with Stock Bypass Valves:

Factory bypass valves have two major shortcomings:

• They leak under high boost, robbing you of power.
• They aren’t optimized for throttle response, causing unnecessary lag.
• They can blow open at high pressure, limiting your turbo’s full potential.

The GFB Mach 2 fixes these issues, giving you better performance, reliability, and efficiency—all without the noise.
