Abstract
An exhaust gas manifold of an exhaust system for an internal combustion engine includes a diverging pipe elbow and exhaust pipes. Each exhaust pipe has an end and is connected to the diverging pipe elbow. The ends of the exhaust pipes extend substantially unidirectionally into the pipe elbow. The sections of the exhaust pipes adjacent to the ends are joined and together form a circular cross section. The portions of the exhaust pipes adjacent to the joined sections are separated from each other with a gap.
