GFB Respons TMS Adjustable BOV
2015-2020 Subaru STI
Respons TMS Direct fit Blow off valve or BOV with GFB TMS advantage. Patented adjustable venting bias system diverter valve.Details
Highlights:- 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).
- Offers better throttle response
- Fast boost recovery on gearshifts
- Unlimited Boost-Holding
Not just any 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 GFB’s patented venting bias adjustment system, the Respons allows you to precisely control how much air vents from each of the two outlets. This unique system allows the amount of air vented to either recirc or atmosphere to be infinitely varied to change the venting sound like a stereo volume dial!
Increase Your Boost by 30%
So if you want noise with your performance, the Respons can deliver! By fine-tuning the venting ratio, you CAN achieve a blow-off sound WITHOUT throwing a CEL (check engine light), running rich, stalling, using more fuel or causing any other problems commonly associated with atmo-venting valves on cars with MAF sensors. 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.

Gives the sound, and no trouble.
I installed this on my 18 STI, it's pretty straightforward and brings out that BOV sound you want The car is perhaps slightly slower between shifts, and with an axle back I can definitely hear popping sometimes after letting off It's probably not ideal considering this is a MAF car, but definitely makes for an exciting drive

Fantastic and easily adjustable
Installed the blow off valve on my 2015 sti and was extremely happy with the performance. The adjustability of the valve is key to ensuring the sti doesn’t throw a CEL.

Awesome product...easy install...great sound!
I just bought a 2015 STI after owning a normal WRX, and the first thing I wanted to get for it was a blowoff valve. I didn't modify my WRX at all and haven't done a lot of performance mods outside of exhausts. After doing some research, I wanted to find a BOV that didn't set off lights on the dash, and that made a great, loud sound. The GFB Respons does just that!! Super easy install. It took all of 10min. The adjustability part of the valve is cool, although I will always keep it all the way open. First drive with it was spectacular and I got so excited when I got onto the freeway and flew through the gears! Definately worth it!! Sounds awesome!!
