EXHAUST PIPE INSTALLATION

PROCEDURE

1. INSTALL FRONT EXHAUST PIPE ASSEMBLY

   
   

   1. 

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

      Minimum

      41.5 mm (1.63 in.)

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

   2. Temporarily install a new gasket to the exhaust manifold converter sub-assembly (TWC: Front Catalyst).

   3. 

      *1	Exhaust Manifold Converter Sub-assembly (TWC: Front Catalyst)
      *2	Gasket
      *a	Wooden Block

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

      Note

      
      

      • Be careful with the installation direction of the gasket.

      • Do not reuse the gasket.

      • Do not damage the gasket.

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

   4. Install the front exhaust pipe assembly to the exhaust manifold converter sub-assembly (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 converter sub-assembly (TWC: Front Catalyst) and front exhaust pipe assembly is consistent front-to-rear and left-to-right.

      

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

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

   
   

   1. Install a new gasket to the front exhaust pipe assembly.

   2. Connect the center exhaust pipe assembly (TWC: Rear Catalyst) to the exhaust pipe support.

   3. Install the center exhaust pipe assembly (TWC: Rear Catalyst) to the front exhaust pipe assembly with the 2 bolts.

      Torque:

      56 N*m  { 571 kgf*cm, 41 ft.*lbf }

3. INSTALL TAIL EXHAUST PIPE ASSEMBLY

   
   

   1. 

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

      Minimum

      41.5 mm (1.63 in.)

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

   2. Temporarily install a new gasket to the center exhaust pipe assembly (TWC: Rear Catalyst).

   3. 

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

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

      Note

      
      

      • Be careful with the installation direction of the gasket.

      • Do not reuse the gasket.

      • Do not damage the gasket.

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

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

   5. Install the tail exhaust pipe assembly to the center 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 center exhaust pipe assembly (TWC: Rear Catalyst) and tail exhaust pipe assembly is consistent front-to-rear and left-to-right.

      

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

8. INSPECT FOR EXHAUST GAS LEAK

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