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 25mm inlet and 25mm outlet.
