Exhaust system for an internal combustion engine

The exhaust system (40) includes a first exhaust tract (11) assigned to a first group of cylinders of the internal combustion engine, and a second exhaust tract (12) assigned to a second group of cylinders of the internal combustion engine. The first exhaust tract and second exhaust tract are coupled to one another by a connecting line (15). A common bypass line (18) branches off from the connecting line for coupling the exhaust tracts. The common bypass line opens to atmosphere downstream of the connecting line, with respect to a direction of flow of exhaust gas (19).
