Abstract
An exhaust system has an exhaust tailpipe cover provided in an outlet region and, on the inside, contains inner exhaust pipes which are disposed spaced apart from the exhaust tailpipe cover by a passage. The passage in the exhaust tailpipe cover results in the exhaust tailpipe cover being exposed to as little thermal loading as possible and avoids transmitting heat to a surrounding vehicle rear part, in particular made of plastic.
