In 2004, GFB released the Whistling Trumpet (part # 5701), which emitted a piercing screech when driving aggressively. For the owners of all other types of GFB valves, we have now released the 5702 – a modified version of the Whistling Trumpet that is designed to work on Mach 1 and all Hybrid variants, and importantly, on low boost applications where the 5701 doesn’t cut it.
