Go Fast Bits T9100 Mach 2 TMS Recirculating Diverter Valve

The Go Fast Bits T9100 Mach 2 TMS Recirculating Diverter Valve is engineered for precision and performance, making it an essential upgrade for Subaru enthusiasts. Designed to replace the factory bypass valve, this unit offers a straightforward installation process—simply remove the stock valve and bolt on the Mach 2 without the need for additional adapters or modifications.

Technical Features

  • Type: 100% recirculating valve (bypass, plumb back)
  • Material: High-quality aluminum construction for durability
  • Finish: Anodized for corrosion resistance and aesthetic appeal
  • Boost Handling: Capable of holding unlimited boost pressure without risk of damage
  • Throttle Response: Optimized with TMS technology for improved throttle response

The Mach 2 diverter valve addresses common shortcomings of factory valves, which often open only above a certain pressure threshold and are not optimized for quick throttle response. The T9100 allows for venting to atmosphere when using the optional conversion kit, providing a balance of performance and sound without the risk of engine stalling.

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and frequently released new models to expect eventual failure and discard something when it stops working or is superseded.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