How to remove and install the exhaust manifold in 3.5L V6 engine for the 2008 Toyota Highlander?

On 2GR-FKS engines, the catalytic converters are integral with the exhaust manifolds, and the following procedure applies to either exhaust manifold. Begin by disconnecting the electrical connectors from the left upstream oxygen sensor. Next, remove the bolts securing the exhaust manifold support bracket and take it off. Disconnect any interfering wire clamps and remove the heat shield from the front exhaust manifold. Evenly loosen the nuts securing each exhaust manifold and then remove the manifold. Discard the old exhaust manifold gasket. For installation, reverse the removal process using a new gasket, ensuring the oval-shaped protruding tip faces the correct direction: it must face to the rear for the left manifold and to the front for the right manifold. Finally, tighten the exhaust manifold nuts gradually, starting from the center nuts and working outward, to the specified torque.
