The invention relates to a double-walled tail pipe which can be pushed onto the end of the exhaust pipe (2) pertaining to an exhaust system of a motor vehicle. According to the invention, the outer wrap (1) is supported against the converter shell (5). The outer wrap (1) and the converter shell (5) are only connected in the overlapping area close to the exhaust pipe, however, are adjacent in the direction of the outlet end of the exhaust pipe without any contact therebetween. A cooling jacket (18) is produced over the entire circumference by the flowing cooling air. Said cooling jacket (18) protects the outer shell from the heat that is radiated by the exhaust gas or the converter shell.
