Abstract: The present invention relates to a sheet-metal-type part, in particular a muffler bottom having at least one through-opening for a tubular part. The sheet-metal-type part has at least one slot passing through the sheet-metal-type part in an area adjacent to the through-opening. The slot runs essentially in the circumferential direction or runs tangentially to the through-opening.

Abstract: An exhaust-carrying component (2) of an exhaust system (1) for an internal combustion engine is provided, in particular for a motor vehicle. The component (2) includes a pipe (4) through which exhaust gas can flow from one longitudinal end (6) to the other longitudinal end (7) and which has between its longitudinal ends (6, 7) a longitudinal section (8), the wall (9) of which is provided with perforations (10). The component (2) also has a housing (5) which surrounds the pipe (4) in a circumferential direction and to which the pipe (4) is fixedly connected in both one end area (11) having a longitudinal end (6) and in another end area (12) having the other longitudinal end (7). In order for the component (2) to nevertheless be able to resist the thermal stresses that occur during operation, the perforations (10) are designed so that the longitudinal section (8) can absorb thermal longitudinal expansion forces between the pipe (4) and the housing (5) through elastic deformation.
