A process for producing exhaust gas manifolds is provided, which have a flange for fastening to the cylinder head of an internal combustion engine, manifold pipes for leading off the exhaust gases flowing from the cylinders, and a pipe connector, wherein the pipe connector has openings for the manifold pipes. In accordance with the invention, the pipe connector is designed with reinforced openings. Then the ends of the manifold pipes are introduced into the openings and expanded. In this process, the pipe ends undergo plastic deformation, and the pipes are connected gas-tight.

Processes for producing exhaust gas manifolds

A device for fastening an exhaust manifold to an internal combustion engine is provided. The device includes two parts. A first part that has first elongated holes for a screw fastening to the engine and openings for a screw fastening of a second bracket part. The second bracket part is fork-shaped, angular, and has on the angle branch facing the first bracket part second elongated holes and on the other angle branch, third elongated holes. The longitudinal axes of at least two of the elongated holes are oriented perpendicular to one another.
