To replace the catalytic converter on a GMC Safari, first, lift the vehicle and secure it on jack stands. Disconnect the exhaust system by unbolting the flanges at both ends of the catalytic converter, ensuring to also detach any oxygen sensors if applicable. Remove the old catalytic converter and install the new one, securing it with gaskets and bolts. Finally, reconnect the exhaust system and any sensors, then start the engine to check for leaks.
