Product Details

If you're looking to change up the sound of your blow-off valve, this Whistling Trumpet from Go Fast Bits is a neat way to do it. It's designed to replace the standard trumpet on specific GFB blow-off valves, like the Stealth FX and WRX Hybrid models, and it makes a distinct whistling noise when the valve releases boost.

To get the best whistling sound, you'll want to make sure your blow-off valve is set up to vent most, if not all, of the air through this trumpet. Valves that are set to vent partially back into the intake might not push enough air through the trumpet to create the whistle. This part is a straightforward swap for the existing trumpet on compatible GFB valves, offering a simple way to customize your car's sound.
