Go Fast Bits Mach 2 TMS Recirculating Diverter Valve Subaru WRX 2008-2014 / Legacy GT 2005-2009

Description:
The Mach 2 is configured as a 100% recirculating valve and add-on kits are also available to convert to 100% atmosphere venting. Use the recirculating model for direct factory replacement when you want the performance WITHOUT the noise! Add the conversion kit when you want some noise with your performance! Factory bypass valves have two main shortcomings – one is that they are typically designed to start opening above a certain pressure to protect the engine, and the other is they are not optimized for throttle response. Oh, and you can’t vent them to the atmosphere without stalling your engine. Mach 2 solves all of these issues. It can effectively hold unlimited boost (unlimited in that no turbo could ever produce enough pressure to damage it), and the TMS technology ensures maximum throttle response. Oh, and you CAN vent with the atmosphere conversion to atmosphere without stalling your engine.
