Abstract (en)
[origin: WO2014195062A1] The invention relates to an exhaust gas system (1) for an internal combustion engine having at least a first and a second cylinder, wherein a first exhaust gas pipe (2) is associated with the first cylinder and a second exhaust gas pipe (3) is associated with the second cylinder and wherein a first muffler (4) is associated with the first exhaust gas pipe (2) and a second muffler (5) is associated with the second exhaust gas pipe (3). A first muffling pipe (2') branches off from the first exhaust gas pipe (2) upstream of a first shut-off element (6), and is fed through the first muffler (4) and leads into the second exhaust gas pipe (3) downstream of a second shut-off element (7), and a second muffling pipe (3') branches off from the second exhaust gas pipe (3) upstream of the second shut-off element (7), is fed through the second muffler (5) and leads into the first exhaust gas pipe (2) downstream of the first shut-off element (6). Because of the embodiment according to the invention, the exhaust gas back pressure in the exhaust gas system is reduced to a minimum.
