GFB Mach 2 TMS Recirculating Diverter Valve - Subaru 2015+ WRX/Forester

This is the Go Fast Bits Mach 2 TMS Recirculating Diverter Valve, designed specifically for your 2015-2020 Subaru WRX. If you're looking to get the most out of your turbo system without adding extra noise, this valve is a solid option. It works by managing the boost pressure released when you shift gears or let off the throttle, helping to maintain boost pressure between shifts for quicker acceleration and better throttle response.

What sets the Mach 2 apart is its ability to handle high boost pressures, well over 100psi, which is more than most turbos can produce. From the factory, it's set up for full recirculation, meaning all the vented air goes back into the intake system. This setup gives you the performance benefits of a diverter valve, like faster boost recovery and improved throttle response, but without the characteristic "pssh" sound you get from atmospheric vent valves. It's a direct bolt-on part, making installation straightforward.

If you're looking for improved turbo performance and boost control on your WRX, the GFB Mach 2 offers a well-built solution that prioritizes function and quiet operation.
