Subaru WRX/STI 97-98 35mm In / 30mm Out HYBRID TMS [GFB]

ALL THE PERFORMANCE WITH THE NOISE!

The Hybrid valve is back! In 1999, GFB™s first Hybrid valve pioneered the dual port design, which was so successful the technology has since been adopted by most brands. By œstaging the two venting outlets, at low valve lifts most of the air is recirculated. As the car is driven harder, the valve opens further and more of the atmosphere venting post is exposed for a louder sound.

As a benefit, this system makes it possible to use these valves on cars with sensitive airflow meters that often suffer issues such as backfiring and/or stalling, whilst still achieving the signature blow-off sound.

The Hybrid then went on to evolve into GFB™s next world-first, the venting bias adjustable BOV now known as the Respons TMS, and then to the electronically adjustable version, the Deceptor Pro.

With the spotlight focused on these current products, the Hybrid has been absent from the market for some time, but in celebration of the 20 years since the invention of one of the most influential BOVs the turbo world has seen, GFB is bringing the Hybrid back!

With the same staged venting outlets as the original, but now with the ability to configure for full recirc, full atmosphere, or 50/50 venting, and a huge range of direct bolt-on kits for popular vehicles, the new Hybrid offers all the benefits of dual port venting, at an affordable price!

Mach Valves: Choose between 1 of 2 options when you purchase it: Full recirculation or full atmospheric venting.

Hybrid Valves: These can do full recirculation, full atmosphere or venting both half way (50/50). So it has 3 settings.

TMS Response Valves: You can adjusts these between any setting of recirculation vs atmospheric venting. So choose 80% recirculation and 20% atmospheric venting, or 70/30, 50/50, 60/40 etc.

Deceptor Pro Valves: This is the TMS Response valve but with the difference that it is adjustable electronically from inside your car with the included GFB controller.
