The GFB Deceptor Pro II blow‑off valve lets you control the ratio of recirculated versus vented air to tailor the blow‑off sound from the driver's seat. Its patented Venting Bias Adjustment System with remote electronic control allows infinite variation of recirculation versus venting and can limit maximum venting to avoid backfire or stalling.
