Mixing path for an exhaust gas system of an internal combustion engine

An exhaust gas system for an internal combustion engine, the exhaust gas system comprising a mixing path;

• and, downstream of said mixing path, an exhaust gas treatment unit;
• and said mixing path including:
• a mixing path housing configured to have exhaust gas flow therethrough in a main direction of flow of the exhaust gas;
• a tubular mixing body defining a mixing body longitudinal axis and being arranged in said mixing path housing and extending in the direction of the mixing body longitudinal axis;
• said mixing body radially outwardly delimiting a first flow volume configured to have the exhaust gas flow therethrough and radially inwardly delimiting a second flow volume configured to have the exhaust gas flow therethrough;
• said mixing body including a tubular first mixing body part having an outer side and extending in a direction of the mixing body longitudinal axis;
• said mixing body including at least one tubular second mixing body part on said outer side of said first mixing body part;
• said outer side facing the second flow volume or an inner side of said first mixing body part;
• said inner side facing the first flow volume or on an inner side of said first mixing body part, said inner side facing the first flow volume;
• said at least one tubular second mixing body part extending in the direction of the mixing body longitudinal axis;
• said second mixing body part having a plurality of first shaped formations arranged adjacent to each other in the direction of the mixing body longitudinal axis and in a circumferential direction about the mixing body longitudinal axis and directed toward said first mixing body part;
• and,
• said second mixing body part abutting said first mixing body part in the region of at least some of said first shaped formations.
