EXHAUST PIPE INSTALLATION

PROCEDURE

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

   
   

   1. 

      Using a vernier caliper, measure the free length of the 2 compression springs.

      Minimum Free Length

      40.5 mm (1.59 in.)

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

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

   3.

      *1	Exhaust Manifold Converter Sub-assembly (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 converter sub-assembly (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 pipe when connecting it.

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

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

      *a	Space between Flanges: 8.5 mm (0.335 in.)

2. INSTALL CENTER EXHAUST PIPE ASSEMBLY

   
   

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

   2. Connect the center exhaust pipe assembly to the exhaust pipe support.

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

      Torque:

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

3. INSTALL TAIL EXHAUST PIPE ASSEMBLY

   
   

   1. 

      Using a vernier caliper, measure the free length of the 2 compression springs.

      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 center exhaust pipe assembly.

      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 pipes when connecting them.

   4. Connect the tail exhaust pipe assembly to the 3 exhaust pipe supports.

   5. Install the tail exhaust pipe assembly to the center exhaust pipe assembly 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 center exhaust pipe assembly and tail exhaust pipe assembly is consistent front-to-rear and left-to-right.

5. INSPECT FOR EXHAUST GAS LEAK

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