An exhaust gas system includes a reducing agent preparation section having a first cylindrical exhaust gas line pipe section opening approximately perpendicularly into a second exhaust gas line pipe section via an opening in a cylinder lateral surface of the second exhaust gas line pipe section. An injector unit for introducing the reducing agent into the exhaust gas is situated at the first exhaust gas line pipe section, upstream from the opening. The opening in the cylinder lateral surface of the second exhaust gas line pipe section has a larger extension in the direction of the longitudinal extent of the second exhaust gas line pipe section than transversely thereto. In a method using the reducing agent preparation section a rotating exhaust gas flow is formed within the second exhaust gas line pipe section.
