Introducing the Mach 2 Bypass Valve
If you're familiar with the Respons and Deceptor Pro II, you'll be excited to know that the Mach 2 is available in a variety of bolt-on kits designed for most popular turbo models. And when we say "bolt-on," we truly mean it! No extra adapters, parts, or modifications to your vehicle are necessary. Just take off the factory bypass valve and pop in the Mach 2—it's as easy as that!
Performance Without the Noise
The Mach 2 is designed as a 100% recirculating valve (also known as bypass or plumb back). If you're looking for a direct factory replacement that delivers performance without the extra noise, this is your go-to option! But if you want to hear that turbo sound, you can grab the conversion kit for 100% atmosphere venting.
Say Goodbye to Common Shortcomings
Factory bypass valves often come with a couple of drawbacks. They usually start opening at a certain pressure to protect your engine, which can be a hassle. Plus, they aren't optimized for quick throttle response. And let’s not forget—you can't vent them to the atmosphere without risking a stall!
The Mach 2 to the Rescue
The Mach 2 addresses these issues head-on. It can handle unlimited boost (well, as much as any turbo could produce without causing damage), and the TMS technology guarantees fantastic throttle response. Plus, with the atmo conversion kit, you can vent to the atmosphere without worrying about 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and frequently released new models to expect eventual failure and discard something when it stops working or is superseded.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.
