Abstract
An end pipe (18) of a tractor exhaust system is adapted for connection to an upright outlet pipe (12) from an exhaust muffler (10) so that when the end pipe (18) or muffler (10) is to be replaced, the pipes (18, 12) can easily be separated. This is achieved by ensuring that only very small areas of the pipes (18, 12) contact each other. The end pipe (18) has an insert (20) therein which has a lower converging frusto-conical portion (24) which acts as a seating for a converging end (14) of the outlet pipe (12). A ring (28) with a convex inner face (in cross-section) is also provided in the end pipe (18) near its lower end. This ring (28) contacts the outer surface of the outlet pipe (12). In this way, the outlet pipe (12) is maintained out of contact with the end pipe (18), except at the ring (28), and the converging end (14) of the outlet pipe.
