GFB T9525 DECEPTOR PRO 2 - IN-CABIN MOTORISED ADJUSTABLE BIAS VENTING DIVERTER VALVE - SEAT LEON MK1 1.8T
Go on, admit it. There are times you wish you could have that signature turbo blow off sound, but you’re not prepared to listen to it all the time. GFB’s Deceptor Pro II delivers just what you need – the ability to control how loud your BOV sound is, from the driver’s seat.
To top it off, if your car typically suffers issues such as backfiring and stalling when venting more than a certain percentage of air to atmosphere, the controller can easily be configured to limit the maximum venting ratio. This way, you can achieve a blow-off sound without having to put up with the issues.
Complete range of fitment options
The Deceptor Pro II direct fit bolt-on range covers a huge list of popular vehicles. You can also purchase a variety of hose and flange adaptors for custom fitments.
