Abstract

Either or both of an exhaust pipe coupled to the output end of an automobile engine collector pipe or the plurality of pipes coupled to the input apertures of the collector pipe from the engine are apertured along their lengths and contained within a further surrounding pipe in providing an exhaust which simultaneously serves as a muffler for the vehicle and to traverse the various component parts of its exhaust system and/or the vehicle engine when composed of a plurality of pipe segments, individual ones of which are of preselected length, and cut at their respective ends at preselected angles for joining together in appropriate orientation.
