The 4.3L, 4.8L, and 5.3L engines utilize a flat flange and a seal on the left exhaust manifold and a ball joint and seal on the right exhaust manifold. The ball joint allows for the system to self-align. A flat flange and a gasket are used at the junction of the rear system and the catalytic converter.
