Beschreibung
Zusammenfassung:	An exhaust system (1) for an internal combustion engine has an exhaust line (2), which has at least one exhaust pipe (3) having a pipe wall (4) with an inner side (5) defining an exhaust gas path (6) guiding an exhaust gas flow (7) and an electric heating device (18) for heating at least one length section of the exhaust pipe (3). An efficient design is obtained if a heating coil (21) is wound several times around the exhaust pipe (3) on an outer side (22) of the pipe wall (4) in the respective length section and has an electric conductor (23) made of a resistance heating material. An electric insulator (24) is arranged between the conductor (23) and the outer side (22) of the pipe wall (4). A heat-insulating cover (25) envelops the exhaust pipe (3) at least in the area of the respective heating coil (21).
