  "textContent": "An exhaust system for an internal combustion engine; the exhaust system comprises: at least one an exhaust duct, which originates from the internal combustion engine; at least one exhaust gas treatment device, which is arranged along the exhaust duct; and a silencing device, which is arranged along the exhaust duct downstream of the exhaust gas treatment device. The silencing device comprises a silencing valve, which intercepts the exhaust duct and is movable between a completely open position and a completely closed position. In the completely closed position, the silencing valve has a first free section for the passage of the exhaust gases having a first area other than zero, so that the exhaust gases can flow through the silencing valve even when the silencing valve is in the completely closed position.",
