    Respons TMS Blow Off Valve by Go Fast Bits

    On the surface it may look like just another dual-port blow-off valve,but the Respons is actually much more than that. Featuring GFB’s patented venting bias adjustment system, the Respons allows you to precisely control how much air vents from each of the two outlets.

    Unlike factory bypass valves, or other brand valves that require different springs for different boost levels, a GFB valve CANNOT be forced open by high boost! The balanced piston design in a GFB valve uses boost pressure on either side to cancel out the forces. Therefore it doesn’t matter how much boost you run, you can be sure a Respons valve will deliver all of it to the engine.

    GFB’s TMS (Turbo Management System) principle is based on an operating method that is different to all factory bypass valves. A factory bypass valve is open until required to shut, however a GFB TMS Valve is shut until required to open.

    Features

    • 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
    • Holds unlimited boost pressure

    Applications

    • 2015+ Subaru WRX STi
    • 2004 - 2014 Subaru Impreza WRX STi
    • 2002 - 2007 Subaru Impreza WRX
    • 2005 - 2008 Subaru Forester XT

    Easy to install, exceptional build quality, and awesome sound

    Total install took longer than it should have just because of the clamp on the re-circulation hose do yourself a favor and just take it off and replace with a hose clamp to make your life easier.

    Great upgrade

    Well built and easy installation. Have had it for a few months and still love it! Great if you want to upgrade your stock BOV and if you want to make noise, if noise isn’t your thing adjust it so it’s fully closed. Awesome product!

    Working as intended

    I choose this bov for the option to choose how the air is released. 1 week in and I'm a happy user.

    Con: only thing I noticed was that it makes a small metal to metal noise when you are revving in low rpms. Like when I was adjusting the screw everytime I would tap the throttle to see the piston I would hear that shuttle slap noise. I watched the gofastbit YouTube video and I even heard the noise in the videos. I just hate extra nosies, but love the bov.
