Abstract

See full text

An exhaust gas system is provided for an internal combustion engine having at least a first and a second cylinder. A first exhaust gas pipe is associated with the first cylinder and a second exhaust gas pipe is associated with the second cylinder. A first muffler is associated with the first exhaust gas pipe and a second muffler is associated with the second exhaust gas pipe. A first muffling pipe branches off from the first exhaust gas pipe upstream of a first shut-off element, and is fed through the first muffler and leads into the second exhaust gas pipe downstream of a second shut-off element. A second muffling pipe branches off from the second exhaust gas pipe upstream of the second shut-off element, and is fed through the second muffler and leads into the first exhaust gas pipe downstream of the first shut-off element.
