Abstract

An exhaust system for an internal combustion engine includes an exhaust gas-carrying component (16) with an outer wall (14), a heat conductor element (12) with a jacket (40) and with a heat conductor device (50) enclosed by the jacket (40). A pass-through device (22) provides a gastight passing of the heat conductor element (12) through the outer wall (14) of the exhaust gas-carrying component (16). The pass-through device (22) includes a pass-through opening (26) in the outer wall (14), which pass-through opening (26) is traversed by the heat conductor element (12), and a connection element (24), which is connected in a gastight manner to the heat conductor element (12), on the one hand, and to the outer wall (14), on the other hand.
