Abstract
An exhaust device () for an internal combustion engine () has an exhaust line () with a rear section X with two exhaust pipes () connected to an acoustic actuator () in a sound-transmitting manner. Better acoustic characteristics and increased number of noises audible from the outside is guaranteed by the exhaust pipes () being of different designs and/or by the actuators () being able to be actuated individually. A process for controlling the actuators () uses a control device () that actuates the actuators () individually to generate different acoustic signals () of the respective actuators (). A motor vehicle () is provided with such an exhaust device () with acoustic actuators () controlled by such a process. The motor vehicle () has additional actuators (), which are especially associated with an intake line () and are arranged in the interior of motor vehicle ().
