Each of the two walls has a circumferential edge area (20, 22) configured for fixing at a circumferential wall of a muffler. An exhaust gas flow unit (26) is arranged between the two walls. The exhaust gas flow unit includes a flow duct area (34) with an exhaust gas outer flow opening (38) to be positioned directed towards an opening in a circumferential wall of a muffler, a first mounting duct area (40) with a first mounting opening (44) for fixing the exhaust gas flow unit at a first wall of the walls, and a second mounting duct area (42) with a second mounting opening (46) for fixing the exhaust gas flow unit at a second wall of the walls.
