Methods and systems are provided for an exhaust tract for vehicles having an internal combustion engine, the exhaust tract including a first exhaust gas aftertreatment device and a metering device arranged downstream therefrom. In one example, a region of the first exhaust gas aftertreatment device which is situated downstream is designed as an SCR region. Further, the metering device is designed to spray a reducing agent onto a side of the first exhaust gas aftertreatment device which faces the metering device, counter to a main direction of flow of an exhaust gas.
