Abstract
Curved inlet pipes, which themselves are assembled from at least two curved individual pipes, are provided in an exhaust manifold with sheet metal inlet pipes from the respective cylinder head outlet to a common exhaust gas outlet. As a result, the sum of the moments of resistance is substantially smaller, especially in the case of short, curved inlet pipes, which prolongs the service life of a sheet metal exhaust manifold.
