A device for manipulating the exhaust outlet noise of a motor vehicle, having an exhaust flap which can be positioned in an exhaust pipe and which can be displaced in oscillatory fashion about an exhaust flap basic position in a defined angle range about the exhaust flap basic position in order to manipulate the exhaust outlet noise, wherein the exhaust flap basic position can be actively adjusted as a function of an engine rotational speed and/or an engine load, and wherein the angle range can be actively adjusted as a function of a frequency to be eliminated or attenuated, or a frequency to be generated or enhanced, of the exhaust outlet noise.
