    GFB Hybrid Blow Off Valve

    $328.50 – $602.10

    Known as the “Hybrid”, this world-first became the flagship model of the newly formed company Go Fast Bits. The two venting ports of this revolutionary valve were staged on the body such that the recirc port opened before the atmo port, helping to prevent backfiring and stalling on cars with a MAF sensor, whilst still giving the signature blow off sound when the car is driven harder.

    GFB Whistling Trumpet

    GFB have released the Whistling Trumpets (part # 5701), which emitted a piercing screech when driving aggressively. Unfortunately for a number of GFB owners, the 5701 trumpet only worked with some valve types.

    For the owners of all other types of GFB valves, GFB have now released the 5702 – a modified version of the Whistling Trumpet that is designed to work on low boost applications where the 5701 doesn’t cut it.
