  4. INSTALL NO. 1 EXHAUST PIPE SUPPORT BRACKET SUB-ASSEMBLY


    1. Install the No. 1 exhaust pipe support bracket sub-assembly to the automatic transmission with transfer assembly with the 2 bolts.

      Torque:
      43 N*m  { 438 kgf*cm, 32 ft.*lbf }
  5. INSTALL FRONT EXHAUST PIPE ASSEMBLY (TWC: Rear Catalyst)


    1. B00759A

      Using a vernier caliper, measure the free length of the compression springs.

      Standard length 40 mm (1.57 in.)
      Minimum free length 38.5 mm (1.52 in.)

      If the free length is less than the minimum, replace the compression spring.

    2. Temporarily install 2 new exhaust pipe gaskets to the front exhaust pipe assembly (TWC: Rear Catalyst) for tail exhaust pipe assembly and tail exhaust pipe LH side.

    3. B00775BC47
      *1 Front Exhaust Pipe Assembly (TWC: Rear Catalyst)
      *2 Exhaust Pipe Gasket
      *a Wooden Block

      Using a plastic hammer and wooden block, tap in each exhaust pipe gasket until its surface is flush with the front exhaust pipe assembly (TWC: Rear Catalyst).

      Note


      • Be sure to install the gaskets in the correct direction.

      • Do not reuse the gaskets.

      • Do not damage the gaskets.

      • Do not push in the gaskets by using the exhaust pipes when connecting them.

    4. Install 2 new exhaust pipe gaskets to the front exhaust pipe assembly (TWC: Rear Catalyst) for exhaust manifold sub-assembly LH (TWC: Front Catalyst) and exhaust manifold sub-assembly RH (TWC: Front Catalyst) side.

    5. Connect the front exhaust pipe assembly (TWC: Rear Catalyst) with 4 new nuts and 4 new bolts.

      Torque:
      39 N*m  { 398 kgf*cm, 29 ft.*lbf }

      Torque:
      43 N*m  { 438 kgf*cm, 32 ft.*lbf }

      Tech Tips

      After installation, check that the space between the flanges of the front exhaust pipe assembly (TWC: Rear Catalyst) and tail exhaust pipe assembly and tail exhaust pipe LH is consistent front-to-rear and left-to-right.
