A vehicle system includes an engine, a transmission, an exhaust system, an adjustable valve, a sensor, and a controller. The engine is configured to propel a vehicle. The transmission is configured to transfer power from the engine to at least one drive wheel. The exhaust system is configured to route exhaust away from the engine. The exhaust system has a catalyst and an outlet. The adjustable valve is disposed within the exhaust system proximate to the outlet. The sensor is configured to observe human gestures. The controller is programmed to receive signals from the sensor indicative of the human gestures while the transmission is in a parked gear. The controller is further programmed to, in response to the sensor observing a first human gesture, increase an operating speed of the engine or adjust the valve to increase a noise output from the outlet of the exhaust system.
