Audi R8 / Lamborghini Gallardo / Huracan Exhaust Valve/Flap Controller

*IN STOCK!* Welcome to the new generation of exhaust valve controller built by Valvetronic Designs for the AUDI R8 and Lamborghini Gallardo. This controller is incredibly easy to install and its 100% plug and play. When this controller is installed you have full control over the factory exhaust valves. If you have an aftermarket exhaust system that retains the factory exhaust valve controller you will be able to control those exhaust valves as well. This controller overrides all factory valve function for 100% control over the valve and maximum sound change with the two modes being 100% valves open or 100% valves closed.   100% REVERSABLE, ALWAYS ABLE TO RETURN TO STOCK AT ANY TIME. FITMENT AUDI R8 V8 AND V10 2008 - 2020+ LAMBORGHINI GALLARDO 2009 - 2013 (ALL VARIANTS) LAMBORGHINI HURACAN 2015 -2020+ (INLCUDES EVO, PERFORMANTE, STO) AUDI RS4 B8 AUDI RS5 B8.5   *IMPORTANT NOTE* For certain Huracan models, OEM suppliers have changed the polarity of the Exhaust valve solenoid. If your controller is not working you may have to swap the pins in the controller. For Huracan STO and EVO, there is a chance you will need to change the Pin on the power side from one side to the other. *Additionally* the controller is shipped to you without the end connector plugged in. We recommend testing with a test light to confirm power and attaching the connector. This is done because once the connector is pinned it is tricky to undo.
