Go Fast Bits BOV Whistler Trumpet Attachment

Simply screw this trumpet into any Go Fast Bits Stealth FX, Deceptor Pro, or TMS Respons and it will produce an aggressive whistle that sets your car apart from others.

In normal driving conditions it gives a typical whoosh sound, but once the revs and boost level rise, a high pitch whistle noise takes over.

Fits: Any Go Fast Bits Stealth FX, Deceptor Pro, or TMS Respons Blow Off Valve
