ABSTRACT:
An exhaust pipe of a front engine mounted transversely to roll about an axis transverse to the longitudinal axis of the vehicle is joined to a tailpipe by an improved high temperature resistant flexible coupling including a spherically surfaced ring seal supported between a tubular end segment of a first pipe and a free end spherical surface on a second pipe; the second pipe having a flange connected thereto and a pair of bolts are resiliently coupled to the flange fixed on the first pipe to bias the spherical lip against a high temperature lubricant surface on the seal to define a joint with minimal resistance to roll motion so that it readily accommodates substantial angular offset between the first and second pipe segments during high temperature exhaust conditions while maintaining a positively sealed surface at the joint.
