Caution: Exhaust may enter the vehicle and cause personal injury if the slip joints are not coated with exhaust system sealer before assembly.

Important: Apply sealer GM P/N 9985020 or equivalent to the slip joint connection.

When installing a new exhaust component on any model, check for proper alignment. Rattles and noise vibrations in the exhaust system are usually caused by the misalignment of parts. When installing the components, leave all bolts and nuts loose until all parts are properly aligned.

The clamp used to connect the catalytic converter to the exhaust muffler is a single nut compression clamp.
