Abstract

An exhaust system includes a mixer assembly unit (26a) with a mixer body (48a) with an incoming flow side (58a) and with an outflow side (60a) and with a plate shaped carrier element (24a) with a radially outward carrier element body (44a). The mixer body includes a plurality of flow deflection elements (62a) and a holding area (70a). The carrier element includes a counter-holding area (46a) connected in substance to a holding area. The mixer assembly unit is arranged in a junction area of two tubular exhaust gas guide elements (14a, 16a). The exhaust gas guide elements include flange shaped coupling sections. The carrier element body is arranged between the flange shaped coupling sections of the exhaust gas guide elements. A coupling element engages the flange shaped coupling sections and extends over the coupling sections on axial sides oriented facing away from one another radially inwards.
