Abstract
In a double-wall tail pipe for an exhaust pipe of a motor vehicle exhaust system comprising an inner shell to be mounted on the exhaust pipe, an outer shell surrounding the inner shell and being supported thereon in spaced relationship to form an annular air space therebetween for conducting cooling air therethrough, a support structure provided with air passages is disposed between the inner and the outer shells in an area where the inner shell is seated on the exhaust pipe when the tail pipe is mounted on the exhaust pipe which support structure interconnects the inner and outer shells in an area which is spaced from the discharge end of the tail pipe.
