GFB Mach 2 TMS Recirculating Diverter Valve - Subaru 08+ WRX / 03-09 GT Legacy / 09-12 XT Forester

This GFB Mach 2 TMS Diverter Valve is configured from the factory for full recirculation, meaning it vents boost pressure back into the intake system. This setup is for drivers who want the performance benefits of a diverter valve, like quicker boost recovery on gear shifts and better throttle response, without the audible 'pssh' sound that some valves make. It's a direct fit bolt-on part for specific Subaru models, making installation straightforward.

The Mach 2 utilizes GFB's TMS Technology, which helps ensure rapid boost recovery. This valve is built to handle boost pressures well over 100psi, which is more than most turbos can produce, so you don't have to worry about it leaking boost under normal operating conditions. While this version is set up for full recirculation, atmosphere venting kits are available separately if you decide you want the sound later.
