摘要： The invention relates to an exhaust component in a gas exhaust line for gases produced by the combustion of a fuel in a heat engine. In the gas flow direction, there is a first connection to an upstream pipe carrying gases from the engine. There is also a first exhaust tube and a second exhaust tube, these two tubes being parallel and being connected to the first connection. There is a second connection to a downstream gas discharge pipe, connected to the parallel exhaust tubes. The component is characterized in that, firstly the first tube has a depolluting component, and the second tube has a silencer. The second connection is a three-way valve.
