The Go Fast Bits Deceptor Pro II blow-off valve for Nissan Silvia and 200SX (S14–S15) lets you control the characteristic turbo venting sound from the driver's seat. Its patented Venting Bias Adjustment System with remote electronic control lets you vary recirculation versus atmosphere venting to tune sound and behavior. Wiring loom is included, it requires a 12V supply, and the venting ratio can be limited to reduce backfiring or stalling.
