Title: Exhaust manifold attachment apparatus and method for fabricating same

Abstract: A flexible connector apparatus for decoupling vibrations, for example, along 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 bellows for accommodating relative movement between the first and second components. The flexible connector apparatus includes an attachment construction which enables weldless, gasketless connection of the bellows to at least one of the first and second components. The flexible connector apparatus may include a liner tube structure having inlet and outlet liner tubes. An alternative construction incorporates a multi-ply bellows in the absence of a liner structure.
