Exhaust gas system

A system for exhaust gas routing and aftertreatment in a motor vehicle includes a first exhaust gas duct element, which has an inlet opening and an outlet opening, and a second exhaust gas duct element, which has a transfer pipe having a longitudinal axis and having a sleeve surface and a first closed end. An intake opening is provided in the sleeve surface adjacent to the closed end. The transfer pipe projects into the outlet opening and is accommodated in the first exhaust gas duct element by its closed end and the intake opening, so that exhaust gas flowing in through the inlet opening in a first direction can flow through the intake opening and into the transfer pipe and flow-viewed in the direction of the longitudinal axis of the transfer pipe-in the transfer pipe through the outlet opening out of the first exhaust gas duct element. The system also includes an injector unit fixed to the first exhaust gas duct element for introducing a reducing agent into an exhaust gas flow flowing through the first and the second exhaust gas duct element.
