The disclosure refers to a static mixer for use in an exhaust system for a combustion engine and for the mixing of an additive injected into an exhaust system. The mixer consists of a tubular housing encircling a central axis X. The housing comprises an input opening at the end in the direction of central axis X and at the opposite end an outlet opening, whereby the inlet opening is used for the supply of additive injected into the exhaust system. The housing is closed in the section of the inlet opening and in the section of the outlet opening in circumferential direction around the central axis X. The static mixer is designed to generate little counterpressure, to guarantee rapid and complete reducing agent preparation and at the same time to be resistant to production tolerances. For this purpose, housing forms a tubular segment related to an XY plane parallel to central axis X of mixer and at right angles to a main flow direction S downstream of the XY plane, which features several openings as perforations orientated in radial direction to central axis X and a tubular segment downstream of the XY plane which features a recess in which several guiding plates are arranged.
