WRX & STI Go Fast Bits Respons Bypass Valve

The Go Fast Bits Respons blow-off/bypass valve system for 02-07 WRX and STI is much more than simply a noise maker or a factory valve replacement. The Go Fast Bits Respons valve features the GFB turbo Management System (TMS),designed specifically for the purpose of turbo lag reduction. Go Fast Bits in-house testing facilities have measured a return to peak boost up to 30% faster between shifts than most factory systems,giving you quicker on-off boost response and faster effective acceleration potential. The Go Fast Bits Response bypass valve features their patented adjustable venting system,allowing you to adjust the sound and vent volume on your valve like a Stereo volume control. Vent or recirculate your boost and turn up or down your Respons volume as you see fit! The unique Respons adjustability allows you to fine tune your turbo system for better drivability while still getting the traditional atmosphere venting noise. Leave those little noise makers behind and upgrade to a system tunable to your Subaru without triggering that dreaded check engine light and compromising daily drivability. This is a direct factory replacement kit that includes everything you need for a complete install with no cutting or further modification to your WRX or STI.
