Abstract: An exhaust system for diesel vehicles is described, which includes at least one metering device for introducing and metering a pollutant-reducing medium into an exhaust gas flowing through a flow pipe of an exhaust tract of an internal combustion engine, in particular for the purpose of introducing a reduction agent and/or a reduction agent precursor, for example urea and/or an aqueous urea solution, the exhaust tract having at least one flexible flange connection.
