Go Fast Bits GFB Whistling Trumpet Suits All Valves

This component enhances the acoustic performance of GFB valves by facilitating a more pronounced whistling sound. Designed as a direct replacement for the standard trumpet, it generates the characteristic whistle at a higher pitch and requires less boost and RPM to activate, unlike its predecessor. For optimal results, it is essential to configure the valve to maximize airflow through the trumpet, as inadequate velocity from Respons valves set to 50/50 venting may hinder sound production. Key Features: Compatible with all GFB valves, ensuring a seamless fit. Produces a distinct whistling sound at lower boost and RPM levels. Delivers a higher-pitched tone compared to similar products. Designed for optimal airflow to maximize sound output. Constructed from durable materials for long-lasting performance.
