An air gap-insulated exhaust manifold (10) for a supercharged internal combustion engine (1), preferably of a motor vehicle has an engine flange (11) fastening the exhaust manifold to an engine block (2) and a turbine flange (12) fastening the exhaust manifold to a turbine (8) of an exhaust gas turbocharger (7). Two inner pipes (13, 14) lead from an inlet opening, for exhaust gas, adjacent to the engine flange to an outlet opening (18), for exhaust gas, adjacent to the turbine flange. An outer pipe (15) envelopes the two inner pipes, forming an air gap insulation (21), and extends from the engine flange to the turbine flange. A separation partition (16) separates, in the interior space (22) of the outer pipe, two interior spaces (23, 24), in which one each of the two inner pipes is arranged. Reduced wear is achieved with the partition arranged loosely at the turbine flange.
