GFB Blow Off Valve Trumpet w/Filter Mount – Universal

Application: Universal
Part Type: Blow Off Valve Trumpet w/Filter Mount


GFB has been building blow off valves and boost control products for enthusiasts and workshops for decades, with a focus on getting the sound and response right without sacrificing reliability. The 5703 trumpet is designed for anyone running a BOV vented to atmosphere who still wants proper protection from the elements, delivering a louder, more distinctive blow-off note than a standard hose barb outlet.

This listing covers the universal 5703 trumpet, suitable for use on GFB SXV, Mach 2, Hybrid, Respons, and Deceptor Pro II blow off valves. It features a 38mm (1.5 in) outlet section that accepts a compatible filter, such as the GFB 5711 (sold separately), to keep dust, sand and mud out of your BOV while enhancing the sound profile.
