NOTE: Do not excessively bend, twist or allow the exhaust to hang from the flexible joint or damage to the exhaust system may occur.

NOTE: Exhaust fasteners are of a torque prevailing design. Use only new fasteners with the same part number as the original. Torque values must be used as specified during reassembly to make sure of correct retention of exhaust components.

All vehicles

Install 6 new RH catalytic converter manifold-to-cylinder head studs.
1. Tighten to 12 Nm (106 lb-in).
