Respons T9000 Diverter / Blow off Valve with Sound Adjustment System for Subaru Applications.
RESPONS TMS : SMARTER THAN A DUAL PORT BLOW OFF VALVE
Atmosphere venting BOV wont work on your car? Try a GFB Respons youll be surprised!
Just another dual-port BOV?
On the surface, it may look like just another dual-port blow-off valve, but the Respons is actually much more than that. Featuring GFBs venting bias adjustment system, the Respons allows you to precisely control how much air vents from each of the two outlets.
Why is this so important? There are two key reasons:
Adjust how loud the blow-off sound is. Recirculate all of the air for silent factory operation, vent it all to atmosphere for maximum noise, or set it ANYWHERE in between to suit your preference.
Get a blow-off sound WITHOUT causing stalling, backfiring, or any other BOV-related issues, even on a car with a sensitive airflow meter (MAF).
Hold on, it gets better. The Respons isnt just a noise-maker. It also:
How GFBs venting bias adjustment works: Twisting the adjusting ring opens up the atmo port, whilst the recirc port is simultaneously closed.This results in possible venting ratios ranging from 100% recirc, right through to 100% atmosphere and anywhere in between.Performance AND sound without compromise!
Adjust the volume of your blow-off sound
Up to 30% faster boost recovery on gearshift
Get the blow off sound without the hassles - even on sensitive MAF-based systems
Hold unlimited boost pressure
Direct bolt-on kits available.

Hold on, it gets better. The Respons isnt just a noise-maker. It also:
- Offers better throttle response
- Faster boost recovery on gearshift
- Unlimited boost-holding! For example, using GFBs TMS (Turbo Management System) principle, tests show that the Respons can return the engine to peak boost up to 30% faster than a factory diverter valve when shifting gears
