Abstract
An automotive vehicle includes an internal combustion engine that generates exhaust gas and an exhaust system that expels the exhaust gas from the vehicle via at least one of a first exhaust conduit and a second exhaust conduit. A disturbance sensor is installed within a cabin of the vehicle, and is configured to detect a disturbance within the cabin and to output a disturbance signal indicative of the disturbance. An exhaust valve has a plurality of positions and adjusts an amount of the exhaust gas delivered to the first and second exhaust conduits. The automotive vehicle further includes an electronic hardware controller in signal communication with the at least one disturbance sensor and the exhaust valve. The controller adjusts the position of the exhaust valve based on the disturbance signal to reduce the disturbance within the cabin.
