GFB Whistling Trumpet - for Deceptor Pro/Response (+12psi)
GFB's whistling trumpet, as the name suggests, gives off a unique high-pitch whistle sound on gearshift.
It is a direct screw-on replacement for the standard trumpet found on most GFB valves, and is recommended for use where peak boost pressure is above 13psi.
Our products are manufactured in Australia and the company is accredited to ISO 9001, which ensures our products meet stringent quality requirements at all stages of manufacture.

SPECIFICATIONS
Trumpet Type: Decptor/Pro Response (+12 psi)
The 5702 can be used in place of the standard trumpet on all GFB valves, and will make the whistling sound more readily than the 5701 (high boost and RPM is required to get the whistle from a 5701), and at a slightly higher pitch.? Like the 5701 however, it is necessary to run the valve so that all (or most) of the air vents through the trumpet ? Respons valves will typically not generate the velocity required to whistle when set to 50/50 venting.
