An exhaust silencer for a motor vehicle is provided. In one example, the silencer comprises a noise-reducing structure and a heat sink to transfer heat from exhaust gases to the exterior of the silencer, the heat sink comprising two regions of fins which define a plurality of flow channels through the heat sink, the flow channels directing the flow of exhaust through the silencer from an inlet passage to an outlet passage. In this way, a temperature of the exhaust is reduced, and the silencer and downstream components of an exhaust system may be constructed of materials of a lower thermal tolerance. |
