Some vehicles were factory-equipped with a one-piece inlet pipe/catalytic converter assembly. Replacement components may vary in design and number of parts.
REMOVAL & INSTALLATION
- Disconnect the negative battery cable.
- Raise and safely support the vehicle using jackstands placed under the frame.
- On cars equipped with an exhaust shield, remove the shield(s).
- Support the exhaust system to prevent component damage during removal.
- Disconnect the downstream injection air hose at the check valve, or the air injection tube at the catalytic converter, if so equipped.
- Separate the Y-pipe or inlet pipe from its adjacent components. This can be done by removing flange mounting bolts or pipe clamps, as equipped.
- Disconnect the muffler and/or tailpipe support brackets, if necessary, to provide sufficient clearance, and remove the Y-pipe or inlet pipe.
- Installation is the reverse of removal. Always use new clamps and replace pipe end-to-manifold packing(s). Always install all parts loosely and align the system so that clearances between the system components and surrounding parts are adequate. Torque support bracket bolts to 14 ft. lbs., flange nuts to 30 ft. lbs. and manifold nuts to 35 ft. lbs.
