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.
