Abstract

A mixer assembly unit, especially for an exhaust system of an internal combustion engine of a vehicle, includes a mixer body (48a) with an incoming flow side (58a) and with an outflow side (60a) and with a plurality of flow deflection elements (62b). A carrier area (24a) is provided radially outwards in relation to a mixer longitudinal axis (L) at the mixer body (48a). The carrier area (24a) has an exhaust gas guide element connection area (72a) for permanent connection to a preferably tubular exhaust gas guide element (16a). Radially outside of the exhaust gas guide element connection area (72a), a flange coupling section (88a) couples with a flange coupling section (98a) of another exhaust gas guide element (14a).
