The exhaust system will vary by model, wheelbase and engine options.

Torque values must be used as specified during reassembly to make sure of correct retention of the exhaust components.

When removing a catalytic converter, support the catalytic converter near the rear outlet. Use caution removing the catalytic converter. Make sure not to damage the manifold output flare, the converter inlet flare or the studs.

During installation, clean the mating surfaces of the manifold outlet flare and the catalytic converter inlet flare. Support the catalytic converter near the rear outlet. Make sure not to damage the manifold outlet flare, the converter inlet flare or the studs. To correctly seat the converter, alternately tighten the exhaust manifold-to-catalytic converter nuts to specification.

To ease removal and installation of the exhaust components, lubricate the insulators using Silicone Lubricant F5AZ-19553-AA (Aerosol) or equivalent meeting Ford specification ESR-M13P4-A.

The exhaust system consists of the components shown in the following illustrations.
