Abstract: An exhaust-gas guiding housing for an exhaust-gas system of an internal combustion engine includes an air inlet housing part through which exhaust gas can flow in an exhaust-gas main flow direction and which has a housing wall surrounding a housing longitudinal axis. At least one air inlet opening is provided in at least one air inlet peripheral region of the housing wall. An inner wall is provided at an inner side of the air inlet housing part, which inner wall, together with the housing wall, defines an air inlet chamber. The at least one air inlet opening is open to the air inlet chamber. At least one air passage opening is provided in the inner wall, and/or at least one air passage opening is formed between the inner wall and the housing wall.
