The heat exchanger insert may include a plurality of pipes around which exhaust gas flows transversely in the inner housing and through at least some of which a coolant of a first cooling circuit flows. At least a portion of the outer housing may be cooled by a second cooling circuit. The second cooling circuit may be separate from the first cooling circuit.
