Rubber deterioration and exhaust hanger insulator bracket separation will occur when using oil or grease-based lubricants on the insulators during operation. The exhaust catalytic converter nuts should be removed first with disposal before tightening each one to 47 Nm (35 ft. lbs.) during installation. You should remove but discard the U-bolt clamp assembly from the Muffler then install it with a torque of 47 Nm (35 ft. lbs.). Remove the two resonator nuts first before discarding them while tightening them to 47 Nm (35 ft. lbs.) once installed. The next step requires removal of the exhaust catalytic converter hanger bracket then extraction of the exhaust catalytic converter and muffler assembly sequence. The installation ends by detaching the converter from the muffler and performing reverse-order removal steps for assembly while adding new gaskets.
