How to Maintain the Muffler on a Mercury Mariner?

Replace and throw out the 2 exhaust catalytic converter nuts before you tighten them to 47 Nm (35 ft. lbs.) during the installation process. The U-bolt clamp assembly must be removed first from the muffler before tightening it to 47 Nm (35 ft. lbs.) during reinstallation. After the removal of 2 resonator nuts install the new ones with a torque of 47 Nm (35 ft. lbs.). Take out the exhaust catalytic converter and muffler as an assembly unit while discarding the catalytic converter exhaust hanger at first.
