ABSTRACT:
A connecting line or exhaust pipe for disposal within the exhaust system of a motor vehicle driven by an internal-combustion engine between the exhaust manifold of the engine and the muffler. The connecting line is formed of two bowl-shaped sheet metal half-shells which are preshaped, e.g., by pressing, deep drawing or the like, and which are superposed on one another, and firmly connected together. The half-shells of the connecting line have a shape such that the connecting line has a non-circular substantially flat cross section with respect to its vertical dimension when the connecting line is connected in the vehicle exhaust system.
