Abstract: The invention is concerned with a slip joint connection between an exhaust manifold attached to an engine which is resiliently mounted to a vehicle frame and an exhaust outlet member which is rigidly mounted to the vehicle frame. The connection comprises an exhaust outlet sleeve rigidly mounted to said engine in flow communication with the manifold having a first peripherally extending portion. The connection further includes a hollow piston having a second peripherally extending portion adjacent a first end thereof and having a generally spherical external surface adjacent a second end thereof, the diameter of the spherical surface being substantially equal to the internal diameter of the sleeve, the second end of the piston being received in generally tight relation within the sleeve. Also a part of the connection is a conduit rigidly mounted in flow communication with the exhaust outlet member and having an inlet end adapted to abut in generally tight relation against the first end of the piston.
