The GFB Respons is an adjustable atmospheric/diverter valve kit for the Nissan Silvia (S14/S15). A patented venting-bias adjustment lets you dial in blow-off sound without the backfiring or stalling that fixed-ratio atmospheric valves can cause. It uses GFB's TMS technology for rapid boost recovery and sharp throttle response.
