Abstract

An exhaust pipe assembly comprises an exhaust pipe extending along a pipe axis and a fastening panel that is mounted to the exhaust pipe. The cross-section of the fastening panel is configured in a curved manner, and two contact surfaces of the fastening panel, which are spaced apart in the circumferential direction, are soldered to the exhaust pipe. A support connected with the fastening panel is arranged between the two contact surfaces of the fastening panel. The fastening panel can be fastened to the exhaust pipe by the following steps: an exhaust pipe and a sheet-metal tab are provided; a soldering material is then captively fixed to the sheet-metal tab; and the sheet-metal tab is then arranged on the exhaust pipe such that the soldering material contacts the exhaust pipe to finally solder the sheet-metal tab to the exhaust pipe.
