Product Details

This Go Fast Bits Deceptor Pro II is an electronically adjustable blow-off valve designed for your 2008-2014 Subaru Impreza, 2003-2009 Subaru Legacy GT, or 2009-2013 Subaru Forester XT. It gives you the ability to change how much air is vented to the atmosphere versus recirculated back into the intake system, all controlled from inside your car. This means you can enjoy that signature turbo sound when you want it, and keep it quiet when you don't.

What sets the Deceptor Pro II apart is its Venting Bias Adjustment System, which allows for infinite control over the vent bias. This is particularly useful if your car sometimes struggles with backfiring or stalling when venting a lot of air. You can set the valve to limit the maximum venting ratio, letting you have the blow-off sound without the common drivability issues. The kit includes a wiring loom and only needs a 12V power supply, making installation more straightforward. It's built in Australia to ISO 9001 standards and can hold over 100 PSI of boost.
