Abstract:

Flexible connector systems are provided for decoupling vibrations between two components of an exhaust system of a vehicle, for example an exhaust manifold and an exhaust down pipe. The flexible connector systems are configured for providing sealed, substantially leak-proof connections which are capable of accommodating axial elongation and contraction, as well as pivoting movements of one component, relative to another component. The flexible connector systems include mating structures which are configured to mate with existing manifold outlet formations, with little or no modification of the exhaust manifold configuration. Ball joint structures and/or resilient mounting materials are used for accommodating pivoting movements. Bellows are provided for accommodating elongation and contraction, while providing sealing enclosure of pipe elements transporting the exhaust gases.
