They're available in many different vacuum ranges to time the system's operation to your specific requirements, and they come in your choice of single-stage, two-stage, and high-flow designs.

The ability to change the sound of a blow-off valve is increasingly becoming an important issue with buyers—who want to sound different from everyone else. Go Fast Bits offers replacement whistling trumpets that deliver a different sound! In 2004, the whistling trumpet was first released, emitting a piercing screech when driving aggressively. These new models can be used in place of the standard trumpet on GFB valves—and will make a unique whistling sound. However, it is necessary to run the valve so that all (or most) of the air vents through the trumpet. Order the model recommended for use with your valve application.

Go Fast Bits Mach 2 upgrade kits convert blow-off valves from recirculating to atmosphere venting. To vent the Mach 2 to atmosphere, you need to ensure the piston stays closed at idle and the recirc hose is plugged. The 5930 Atmosphere Conversion Kit includes a 30mm hose plug to block off the recirc hose, a trumpet to replace the hose outlet on the Mach 2 (not necessary for functionality, but makes the sound louder!), and a firmer spring. The Mach 2 is supplied with a softer spring that's suitable for recirculation venting or cars with idle vacuum of 18inHg or less. If the piston stays closed with the existing spring in the Mach 2, there is no need to swap it out. However, if the piston hovers open at idle even with the spring pre-load maxed, the firmer spring in this kit should be installed to prevent stalling or backfiring.
