2. INSTALL FRONT EXHAUST PIPE ASSEMBLY (TWC: Rear Catalyst)

   
   

   1. 

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

      Standard Length	43.0 mm (1.69 in.)
      Minimum Free Length	41.5 mm (1.63 in.)

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

   2. Temporarily install a new exhaust pipe gasket to the exhaust manifold (TWC: Front Catalyst).

   3. 

      *1	Exhaust Manifold (TWC: Front Catalyst)
      *2	Exhaust Pipe Gasket
      *a	Wooden Block

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

      Note

      
      

      • Be careful with the installation direction of the exhaust pipe gasket.

      • Do not reuse the exhaust pipe gasket.

      • Do not damage the exhaust pipe gasket.

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

   4. Connect the front exhaust pipe assembly (TWC: Rear Catalyst) to the 2 exhaust pipe supports.

   5. Install the front exhaust pipe assembly (TWC: Rear Catalyst) to the exhaust manifold (TWC: Front Catalyst) with the 2 compression springs and 2 bolts.

      Torque:

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

      Tech Tips

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

      

      *1	Exhaust Manifold (TWC: Front Catalyst)
      *2	Front Exhaust Pipe Assembly (TWC: Rear Catalyst)
      *3	Exhaust Pipe Gasket
      *a	Space between Flanges: 8.5 mm (0.335 in.)

   6. Engage the wire harness clamp.

   7. Connect the heated oxygen sensor connector.

3. INSTALL TAIL EXHAUST PIPE ASSEMBLY

   
   

   1. 

      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 a new exhaust pipe gasket to the front exhaust pipe assembly (TWC: Rear Catalyst).

   3. 

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

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

      Note

      
      

      • Be careful with the installation direction of the exhaust pipe gasket.

      • Do not reuse the exhaust pipe gasket.

      • Do not damage the exhaust pipe gasket.

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

   4. Connect the tail exhaust pipe assembly to the 4 exhaust pipe supports.

   5. Install the tail exhaust pipe assembly to the front exhaust pipe assembly (TWC: Rear Catalyst) with the 2 bolts and 2 compression springs.

      Torque:

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

      Tech Tips

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

      

      *1	Front Exhaust Pipe Assembly (TWC: Rear Catalyst)
      *2	Tail Exhaust Pipe Assembly
      *3	Exhaust Pipe Gasket
      *a	Space between Flanges: 6.5 mm (0.256 in.)

6. INSTALL FRONT FLOOR COVER RH

   Tech Tips

   Perform the same procedure as for the front floor cover LH.

7. INSPECT FOR EXHAUST GAS LEAK

   If gas is leaking, tighten the areas necessary to stop the leak. Replace damaged parts as necessary.

   Tech Tips

   Perform Inspection After Repair after repairing an exhaust gas leak.
