For replacement, spray penetrant on exhaust pipe-to-exhaust manifold bolts and clamp bolts to loosen them up. Disconnect and remove oxygen sensors. Unscrew upper exhaust pipe-to-exhaust manifold flange bolts and loosen the clamp securing the slip joint between the two sides of the crossover pipe. If replacing the right catalytic converter, also loosen the clamp securing the slip joint between the right exhaust pipe and the premuffler. Remove the catalytic converter assembly, discard the old flange gasket, and install a new one during reinstallation using new bolts and clamps as recommended by Dodge. Coat threads with anti-seize compound for ease of future removal and tighten all fasteners securely.
