Product Details

Go Fast Bits is known for making well-built performance parts for turbocharged cars. This Whistling Trumpet is an accessory designed to change the sound your blow-off valve makes. If you're looking to give your car a unique sound, this part can help you achieve a more noticeable whistling noise compared to the standard trumpet.

This trumpet is designed to make the whistling sound more readily, even at lower boost levels, and at a slightly higher pitch than other options. For the best results, the blow-off valve needs to be set up so that most of the air vents through the trumpet. Keep in mind that some valves, like Respons valves set to 50/50 venting, might not produce enough air velocity to create the whistle.

This part is not CARB approved and cannot be shipped to California. It's intended for low boost applications and suits all valves except the DV+ model.
