APR 15-20 Audi S3/16-21 Audi TTS Quattro/15-19 Volkswagen Golf R 2.0T Exhaust Valve Remote - MS100170

The APR Exhaust Valve Remote lets you override the factory exhaust valve operation to fully open the exhaust valves at the press of a button. Simply plug-and-play and press "ON" to open the valves fully. To return to the original behavior, press "OFF" and the valves will operate as if the device wasn't installed. This system works with both the factory exhaust and the APR Valved Catback Exhaust System.
