<p>EXHAUST SYSTEM PIPE AND EXHAUST SYSTEM WITH SUCH A PIPE 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 oulet pipe.</p> |
