T9007 Respons TMS Blow-Off Valve

The Go Fast Bits T9007 Respons TMS is a direct-fit blow-off valve designed to improve turbocharger performance and sound customization. It features GFB's patented venting bias adjustment system, allowing the user to infinitely vary the ratio of air vented to atmosphere versus recirculated air. This unique capability enables control over the blow-off sound, from completely silent operation to maximum noise, without causing issues like stalling or backfiring, even on sensitive MAF-based systems. Beyond sound customization, the Respons TMS utilizes GFB's Turbo Management System (TMS) principle to enhance engine performance. This blow-off valve is designed as a direct bolt-on kit, fitting directly into the factory location without requiring modifications to the car. It is specifically listed as a direct fit for various Subaru WRX models from 2015-2021 and Subaru Forester 2.0XT models from 2014 onwards. Installation requires access from underneath the vehicle, necessitating raising the car on ramps, axle supports, or a hoist.
