Go Fast Bits Respons Bypass Valve: WRX (2002-2007) STI (2004-2021)

It may look like just another dual-port blow-off valve, but the Respons from GFB for the Subaru 2002-2007 WRX and 2004-2021 STi is much more than that. Featuring Go Fast Bits’ patented venting bias adjustment system, the Respons BOV allows for precise control of how much air vents from each outlet. Do you want that amazing BOV sound? Of course you do - why else would you be researching this BOV from Go Fast Bits! Now you can dial in the sound level. This feature allows you to adjust how loud the blow off valve sounds when installed in your Subaru. Recirculate all of the air for silent factory operation, vent it all to the atmosphere for maximum noise, or set it anywhere in between to suit preference. Get a blow off sound without causing stalling, backfiring, or any other BOV related issues, even on a Subaru with a sensitive airflow meter. This BOV will give your Subaru WRX/STI better throttle response, faster boost recovery on gearshift, and unlimited boost-holding.
