Abstract: An air guiding arrangement is integrated into a rear underbody of a motor vehicle that is driven by an internal combustion engine. The air guiding arrangement includes a final silencer (1) in an exhaust system (3.1, 3.2, 3.3, 3.4, 4.1, 4.2). The final silencer (1) has an underside that faces an underlying surface on which the vehicle is supported. The underside of the final silencer (1) is shaped in an aerodynamic fashion with at least one duct (6) that runs essentially in the direction of travel (X). The duct (6) has an inverted U shape or inverted V-shape that is open in the underside of final silencer (1). Air deflector elements (7, 8, 9) may partly cover the air duct (6) for guiding the air flow.
