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.
