Abstract

The invention relates to a mixer for an exhaust gas system for mixing an additive into an exhaust gas flow of an internal combustion engine, having a first shell and at least a second shell which are arranged successively in the circumferential direction in relation to a center axis, each shell having at least two shell edges that are arranged offset in the circumferential direction and which each form a flow edge, wherein the flow edges of two circumferentially adjacent shell edges of two different shells delimit an inflow opening, such that at least one pipe end arranged coaxially with the center axis is provided with a circumferential pipe profile that has a nominal radius Rn and is used for connection to an exhaust pipe, the pipe end being formed by the circumferentially adjacent shells.
