CAUTION: When repairing the exhaust system or removing exhaust components, disconnect the heated oxygen sensors (HO2S) at the wiring harness to prevent damage to the sensors and harness.
Inspect the muffler inlet pipe and resonator for cracked joints, broken welds and corrosive damage that could result in exhaust system leaks. If necessary, replace the muffler inlet pipe and resonator.
Position the muffler inlet pipe and resonator and push the exhaust hanger insulator into the mounting hooks.
Install a new exhaust converter outlet gasket between the TWC and the muffler inlet pipe and resonator.
Install the TWC to muffler pipe and resonator bolts and nuts.
