Product Details

The Go Fast Bits Deceptor Pro II is a motorized blow-off valve designed for your 2015-2020 Subaru WRX, allowing you to control the sound of your turbo's air release right from the driver's seat. This means you can enjoy that signature turbo flutter when you want it, and keep it quiet when you don't, all without needing to physically access the valve itself.

This valve uses Go Fast Bits' patented Venting Bias Adjustment System, which lets you infinitely change how much air is recirculated back into the intake versus how much is vented to the atmosphere. It's built to hold over 100 PSI of boost, so it can handle the demands of a tuned turbo system. The kit includes a wiring loom and only needs a 12V power source, making installation more straightforward. It's manufactured in Australia to ISO 9001 standards, indicating a focus on consistent build quality.

If your WRX has experienced issues like backfiring or stalling when venting a lot of air, the Deceptor Pro II's controller can be set to limit the maximum venting ratio. This helps you get the blow-off sound without the unwanted side effects. This part is not CARB approved and cannot be shipped to California.
