Go Fast Bits Mach II Diverter Valve and atmosphere option for the performance-minded
ALL THE PERFORMANCE WITH OR WITHOUT THE NOISE! GFB's Mach 2 utilises GFB's proven TMS Technology to ensure rapid boost recovery on gearshift and optimum throttle response, as well as the ability to withstand boost pressures of 100 psi plus. Put simply, it can hold more boost than any turbo could produce. With its single venting outlet, the Mach 2 is configured from the factory for full recirculation (i.e. plumb back, diverter, bypass) venting for the performance-minded who just want the benefits without the sound.; The Mach 2 direct fit bolt-on range covers a huge list of popular vehicles. You can also purchase a variety of hose and flange adaptors for custom fitments. Please check the application guide to find the Mach 2 model for YOUR car!
