Introducing the Mach 2 Bypass Valve
If you're looking for a reliable upgrade for your turbo model, the Mach 2 is here to impress! Just like the Respons and Deceptor Pro II, the Mach 2 comes with a variety of bolt-on kits that fit most popular turbo models. And when we say "bolt-on," we truly mean it! You won’t need any extra adaptors, parts, or modifications to your vehicle. Simply take off the factory bypass valve and pop in the Mach 2—it's that easy!
Recirculating or Atmosphere Venting?
The Mach 2 is designed as a 100% recirculating valve, meaning it’s perfect for those who want performance without the extra noise. If you’re in the mood for a bit of sound with your power, you can easily switch to atmosphere venting with our add-on conversion kit. The choice is yours!
Say Goodbye to Factory Bypass Valve Limitations
Factory bypass valves often come with two major drawbacks. They usually start opening at a specific pressure to protect the engine, which can hinder your performance. Plus, they aren’t optimized for quick throttle response. And let’s not forget—you can’t vent them to atmosphere without risking a stall!
The Solution: Mach 2
The Mach 2 addresses all these concerns. It can handle unlimited boost—no turbo could ever create enough pressure to cause damage. Thanks to TMS technology, you’ll enjoy maximum throttle response. And yes, you can vent to atmosphere with the conversion kit without stalling your engine!

We live in a throw-away society, conditioned by cheap products and frequently released new models to expect eventual failure and discard something when it stops working or is superseded. However, pride in workmanship and our commitment to quality means that when we put our name to something, we are also staking our reputation on it.
That’s why we back our products with the best Warranty in the business! You should expect a lifetime of use from a well-engineered product, so if your GFB product fails as a result of defective materials or faulty workmanship whilst you remain the original owner, we will repair or replace it.
If the fault occurred as a result of usage outside of the terms of the warranty, or you are not the original owner, fear not, we can still help you. You should never need to throw a GFB product away, as spare parts are available and won’t cost the earth.
