GFB Deceptor Pro II Blow Off Valve - 35mm Inlet / 30mm Outlet

The GFB Deceptor Pro II is an electronic blow off valve that lets you control the volume of the blow-off sound from the driver's seat. It can also be configured to limit the maximum venting ratio, so cars prone to backfiring or stalling can still run an atmospheric sound without the drivability issues. The wiring loom is included. This version uses a 35mm inlet and 30mm outlet.
