Disconnect the downstream oxygen sensor connectors and remove the under-vehicle splash shield if equipped. Unbolt the exhaust pipes at the exhaust manifolds.

Remove all gasket material from mating surfaces carefully to avoid scratching, and inspect for warpage using a straightedge and feeler gauge; any excessive warpage requires replacement or resurfacing.

Start by raising the vehicle and securing it on jackstands. If applicable, spray penetrating oil on nuts and bolts for easier loosening. For 2.4L engines (2014 and earlier), remove the oxygen sensor and rear portion of the exhaust system, then detach the converter from the exhaust manifold. For 2.7L engines, remove the front exhaust manifold/catalytic converter by disconnecting oxygen sensors and other components. For rear exhaust manifold/catalytic converter, remove the engine cover, splash shield, crossunder pipe, and oxygen sensors. For 3.5L engines, remove the front and rear exhaust manifold/catalytic converters by disconnecting oxygen sensors and other fasteners. For 3.6L engines, remove the rear catalytic converter by loosening clamps and fasteners, then guide the converter out from the bottom. Before installing the converter, use anti-seize compound on threads and tighten the fasteners securely. Installation is the reverse of removal for all models.

After completing the installation, start the engine and check for exhaust leaks between the manifold and cylinder head as well as between the manifold and exhaust pipe.

The first step is to raise the vehicle and secure it on jackstands.

First, disconnect the negative battery cable from the remote ground terminal.

Use anti-seize compound on threads and tighten the fasteners securely.

Tighten the mounting bolts starting in the middle and working outward in several increments to the specified torque.
