How do I change the sound of the blow-off valve?

The GFB Hybrid TMS Dual Port valve comes with a pair of blanking plugs. You can use these plugs to configure the valve for full recirculation, a 50/50 split between recirculation and atmosphere venting, or full atmosphere venting to achieve your desired sound.

Will this valve cause issues with my car's airflow meter?

No, the Hybrid valve is specifically designed to be used on cars with sensitive airflow meters. Its dual venting system helps prevent common issues like backfiring and stalling that can occur with other types of blow-off valves.

What is the benefit of TMS technology?

The Turbo Management System (TMS) technology in this valve helps your turbocharger recover boost more quickly after you shift gears. This can lead to improved throttle response and a more consistent power delivery.

Product Details

If you're looking to fine-tune the sound and performance of your 2008-2014 Subaru Impreza, the Go Fast Bits Hybrid TMS Dual Port valve is a solid option. This isn't just another blow-off valve; it's designed to give you control over both the sound and how quickly your turbo spools back up after a gear change. It works by using two venting outlets that can be adjusted to vent all the air back into the intake, just to the atmosphere, or a mix of both. This flexibility is great because it means you can get that signature blow-off sound without causing issues on sensitive airflow meters, which can sometimes lead to backfiring or stalling.

What makes this valve unique is its TMS (Turbo Management System) technology. This system helps your turbo recover boost up to 30% faster after you shift gears. The Hybrid valve itself is a well-built unit that comes with plugs so you can easily switch between full recirculation, a 50/50 split, or full atmosphere venting. This means you can dial in the sound from quiet to loud, or anywhere in between, depending on your preference or driving situation. It's a direct fit bolt-on part, making installation straightforward.
