GFB Mach 2 TMS Recirculating Diverter Valve Direct Fitment Subaru 99-00
$190.80

Introducing the Mach 2 Bypass Valve

If you're looking for a seamless upgrade for your turbo model, the Mach 2 is here to impress! Just like our popular Respons and Deceptor Pro II, the Mach 2 comes in a variety of bolt-on kits that fit most turbo models. And when we say "bolt-on," we mean it—no extra adapters or modifications needed! Simply take off your factory bypass valve and pop in the Mach 2. It's that easy!

Two Configurations for Your Needs

The Mach 2 is designed as a 100% recirculating valve, which means it operates in a plumb-back configuration. If you're after that sweet sound of venting to the atmosphere, we've got you covered with add-on kits to make the switch! Use the recirc model for a direct factory replacement when you want performance without the noise. Want to turn heads? Go for the conversion kit and enjoy a little more auditory excitement with your performance!

Say Goodbye to Factory Valve Shortcomings

Factory bypass valves can be a bit of a letdown. They usually open at a certain pressure to protect your engine, but that can compromise throttle response. Plus, venting them to the atmosphere can stall your engine—definitely not ideal!

The Mach 2 takes care of all these issues. It can handle unlimited boost (trust us, no turbo will ever produce enough pressure to damage it), and with TMS technology, you’ll experience maximum throttle response. And yes, you can vent to the atmosphere with the conversion kit without worrying about stalling your engine!

Who is Go Fast Bits?

It all started with the passion of John Adrian to create something that other aftermarket parts cannot produce. Most parts he encountered are either of low quality and are made out of inferior materials.

He decided to take matters into his own hands and started designing, testing, and developing parts that would help improve the performance of his vehicle. Using his own car as a personal testbed, he created products that other enthusiasts later noticed, which has become the start of Go Fast Bits.

The company offers various performance parts such as boost controllers, blow-off valves, short shifters, pulley kits, and more. John Adrian also acts as the chief engineer of the company.

Lifetime Warranty
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and frequently released new models to expect eventual failure and discard something when it stops working or is superseded.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.
