Go Fast Bits GFB Whistling Trumpet for Stealth FX and WRX Hybrid

This component enhances the acoustic characteristics of GFB valves by replacing the standard trumpet with a specially designed unit that produces a distinctive whistling sound. It is optimized for use with GFB valves (part numbers T9003 & T9503) and is particularly effective when the valve is configured to allow most airflow through the trumpet. It's important to note that a valve set to 50/50 venting may not achieve the desired whistling effect due to insufficient air velocity. Key Features: Direct replacement for standard trumpet on compatible GFB valves. Produces a unique whistling sound for enhanced acoustic performance. Designed for optimal airflow to ensure maximum sound output. Constructed with durable materials for long-lasting performance. Easy installation with no modifications required for compatible models. Ensure that your setup maximizes the valve's capabilities by running it primarily in a mode that channels airflow through the trumpet. This
