A process for manufacturing an exhaust system, especially for an internal combustion engine of a vehicle, includes providing an exhaust gas-guiding component (26) with a wall (38) made of a metallic material and providing a sensor-mounting connector (22), to be fixed at the wall. The sensor-mounting connector includes a sensor-mounting area (28) to be positioned outside the exhaust gas-guiding component, and a connection area (34), which is to be positioned such that the connection area meshes with the wall. The connection area is pressed against an outer surface (40) of the wall of the exhaust gas-guiding component in a fastening area (39) of the wall, and at the same time rotated about a longitudinal axis (A) of the connector to penetrate into the material forming the wall and a connection in substance is established between the metallic material of the wall and the metallic material of the sensor-mounting connector.
