  4. Support the three way catalytic converter.

  5. Object Number: 107810  Size: SH
  6. Remove the bolts, hangers, and the insulators, as used.
  7. Notice: Cuts must be made as close to the welds as possible in order to ensure adequate overlap for clamping.

  8. Cut the intermediate exhaust pipe from the muffler.
  9. Remove the intermediate exhaust pipe and the bolts/screws from the three way catalytic converter.

  6. Tighten

    1. Tighten the clamp nut to the 50 N·m (37 lb ft).
    2. Tighten the intermediate exhaust pipe bolts/screws to 47 N·m (35 lb ft).

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  7. Lower the vehicle.
