The Respons TMS valves take the Hybrid dual-outlet concept a step further, featuring GFB's patented Venting Bias Adjustment System. This unique feature allows you to infinitely vary how much air is recirculated or vented to atmosphere, like a volume control. Simply by twisting the adjustment ring, you can change the sound of your BOVs from silent to ear-shattering, or anywhere in between.

The Respons isn’t just a noise-maker. It also;

Offers better throttle response
Faster boost recovery on gearshift
Unlimited boost-holding!
