Claim:
1. An exhaust gas system for exhaust gas routing and exhaust gas aftertreatment in a motor vehicle, the system comprising: a first exhaust gas duct element, which has an inlet opening and an outlet opening; a second exhaust gas duct element, which has a transfer pipe with a longitudinal axis, a sleeve surface, and a first closed end, wherein the sleeve surface includes an intake opening adjacent to the first closed end, wherein a portion of the transfer pipe, which includes the first closed end and the intake opening, projects into the outlet opening and is accommodated in the first exhaust gas duct element so that exhaust gas flowing in through the inlet opening in a first direction flows through the intake opening and into the transfer pipe and flows—viewed in a 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, wherein the system further comprises an injector unit fixed to the first exhaust gas duct element and is in direct contact with the transfer pipe, the injector unit configured to introduce a reducing agent into an exhaust gas flow flowing through the first and the second exhaust gas duct elements, and wherein the longitudinal axis of the transfer pipe lies perpendicular to the first direction, and the injector unit is arranged to inject reducing agent into the first exhaust gas duct element upstream of the intake opening and the reducing agent is mixed with the exhaust gas flow before the exhaust gas flow enters the transfer pipe through the intake opening.
