Abstract
In an exhaust system of a motor vehicle, a tailpipe cover is disposed on the exhaust pipe and protrudes through a cutout in the vehicle rear part with a defined gap clearance. In a hot condition, where a length of the exhaust system is increased due to thermal expansion, a greater clearance arises between the edge of the cutout and the tailpipe cover than in the cold condition. The tailpipe cover is trumpet cone shaped.
