The GFB 5701 Whistling Trumpet is a specialized accessory designed to replace the standard trumpet on select GFB blow-off valves. This component is engineered to produce a signature whistling sound during atmospheric venting by utilizing high-velocity air discharge.

For the best acoustic results, the valve must be configured so that all or most of the air vents through the trumpet. Please note that GFB Respons valves typically do not generate the air velocity required to trigger the whistle when set to a 50/50 venting bias.

  • Direct replacement for trumpets on GFB part numbers T9003 and T9503
  • Compatible with GFB Stealth FX and WRX Hybrid valve series
  • Designed for maximum air velocity to ensure consistent sound
  • Manufacturer Part Number: 5701
