Abstract

An encased catalyst, especially for motor vehicles, includes at least one metal honeycomb catalyst carrier body through which exhaust gas can pass. At least one inner jacket tube carries the at least one catalyst carrier body. An outer jacket tube approximately concentrically surrounds the at least one inner jacket tube at a distance. The at least one inner jacket tube and the outer jacket tube have end regions and are firmly joined together in one of the end regions. The at least one inner jacket tube is freely longitudinally expandable in the outer jacket tube.
