Exhaust Valve Simulator

If you love the raw sound of your car in sport mode and want it available 24/7, or if you have an aftermarket exhaust that doesn't utilize the factory exhaust valve, the GrimmSpeed Exhaust Valve Simulator is the solution. By preventing the ECU from throwing a soft code, this simulator allows you to retain the ability to select various drive modes, such as Sport and Track, even after disconnecting the factory exhaust valve actuator. The simulator features a simple installation process: disconnect the current exhaust valve actuator motor while in the open position, plug in the GrimmSpeed simulator into the wiring harness, and zip-tie the exhaust defeat and wiring harness out of the way. The GrimmSpeed Exhaust Valve Simulator boasts a durable finish that resists discoloration and features a weatherproof sealed connector. It offers a clean and refined solution without bulky mechanical simulators and ensures no codes or Check Engine Lights (CEL) are triggered. Vehicle Fitment includes: 2016+ Ford Focus RS, 2015+ Mustang GT350/GT350R, 2015+ Audi S3, 2013-2016 Audi S6, 2014-2016 Audi SQ5, 2015+ Volkswagen Golf R, and other vehicles utilizing the style of exhaust valve actuator shown, with the exception of Dodge models.
