Abstract 1. Field of the Invention Vibration decoupler apparatuses, for decoupling vibrations, for example, between first and second the components of an internal combustion engine exhaust system. The flexible connector apparatus is provided for connecting first and second components in the exhaust system, and includes a resilient flexible sealing member (bellows) for accommodating relative movement between the first and second components. The flexible connector apparatus includes an annular vibration damping member connecting a down pipe to a mounting member for permitting restricted axial, lateral and angular movement of the downpipe, relative to the mounting member, which may be affixed to an exhaust manifold, for example. The apparatus also includes a sealing construction which enables weldless, gasketless connection of the bellows. An alternative construction positions the vibration damping member between the decoupler apparatus and the downstream component. The damping member and the resilient flexible sealing member may additionally be axially separated.
