摘要：An exhaust system is provided for an internal combustion engine having at leasta first and a second cylinder, wherein the first cylinder is assigned a first exhaust gas pipe

and the second cylinder is assigned a second exhaust gas pipe. The first exhaust gas pipeis assigned a first muffler, and the second exhaust gas pipe is assigned a second muffler.A first damping pipe branches off from the first exhaust gas pipe upstream of a first shut-off element. The damping pipe firstly opens into a first reflection chamber and issubsequently led through the first muffler and opens into the second exhaust gasmanifold downstream of a second shut-off element. A second damping pipe branches offfrom the second exhaust gas pipe upstream of a second shut-off element. The seconddamping pipe firstly opens into a second reflection chamber and is subsequently ledthrough the second muffler and opens into the first exhaust gas pipe downstream of thefirst shut-off element.
