A mass damper method includes providing an electroactive polymer (7) and using the electroactive polymer (7) to manufacture a mass damper (6). The mass damper (6) for damping a vibrating system of a motor vehicle includes at least one of a damping body (10) forming a countervibrating mass with a damping spring (11) and a springy damping body (10) forming the countervibrating mass. The damping body (10) is indirectly or directly coupled with the vibrating system. The springy damping body (10) or the damping spring (11) includes an electroactive polymer (7). A motor vehicle exhaust system of an internal combustion engine is provided including an exhaust gas line (3) with an exhaust pipe (4), an exhaust gas-treating device (5) integrated in the exhaust pipe and the mass damper (6) coupled with the exhaust gas line.
