Beschreibung
Zusammenfassung:	The invention relates to an exhaust system (10) for an internal combustion engine, having an exhaust gas path which, at least in sections, has two parallel exhaust ducts (30, 32), specifically a main duct (30) and a secondary duct (32), wherein a HC adsorber (42) for the reversible adsorption of unburned hydrocarbons (HC) is provided in the secondary duct (32); having a setting means (46) for selectively conducting an exhaust gas flow into the main duct (30) and/or into the secondary duct (32), and having a main catalytic converter (40) arranged downstream of the parallel exhaust ducts (30, 32). It is intended that a catalytic exhaust gas converter (44) for converting at least one exhaust gas component is provided in the main duct (30) of the parallel exhaust ducts (30, 32).
