Abstract:
The present invention relates to an exhaust manifold for an internal combustion engine, in particular in a motor vehicle, comprising a housing from which a plurality of inlet pipes emanate, which, in the built-in state, lead to cylinders of the internal combustion engine, and comprising a flange, which is welded to the inlet pipes and which, in the built-in state, is screwed to the cylinder head of the internal combustion engine by means of a screw connection. The fatigue strength of the exhaust manifold can be improved by subdividing the flange into at least two partial flanges in a longitudinal direction of the exhaust manifold.
