Product Details

If you're driving a 2001-2014 Subaru Impreza and want to control the sound of your turbo's blow-off valve, the Go Fast Bits Deceptor Pro II is a solid option. This electronic blow-off valve allows you to adjust how much air is vented to the atmosphere, giving you that signature turbo sound when you want it, and a quieter operation when you don't. It's a neat way to manage the noise without sacrificing the turbo's performance.

What sets this valve apart is its patented Venting Bias Adjustment System, which you can control electronically right from your driver's seat. This means you can dial in the exact amount of blow-off sound you prefer, from a full vent to a near-complete recirculation. 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 handle boost pressures over 100 PSI, so it's well-built for the job.

This valve also has a useful feature for managing potential drivability issues. If your car sometimes backfires or stalls when venting a lot of air, you can configure the controller to limit the maximum venting ratio. This helps you enjoy the blow-off sound without dealing with those annoying side effects. Keep in mind this part is not CARB approved and cannot be shipped to California.
