Abstract (en)

[origin: WO2015172910A1] The invention relates to an exhaust system for internal combustion engines having an exhaust tract, which has at least one first flow path and a second flow path for an exhaust gas stream, wherein the first and the second flow path extend fluidically separated from each other from a pre-silencer to at least one end silencer. Depending on the rotational speed of the motor, the first flow path can be continuously closed by way of a controllable flap, wherein the exhaust gas stream is guided through the second flow path when the flap is closed.
