Abstract
An underbody trim for the rear-end region of a motor vehicle conceals a rear exhaust muffler. For the purposes of cooling the rear exhaust muffler, an air inlet is provided in the underbody trim. The air inlet is arranged in a region in which, while the motor vehicle is traveling, a pressure is higher at the underside of the underbody trim than the region of the floor panel arranged thereabove. Cooling ambient air is thus conducted into the region of the rear exhaust muffler with low flow losses.
