Installation [03/2018 - ]: Procedure

Refer to PROCEDURE - Step 1

See step  11

1. Install 2 new exhaust pipe gaskets to the front No. 3 exhaust pipe sub-assembly.
2. Install the front No. 3 exhaust pipe sub-assembly to the front exhaust pipe assembly and exhaust manifold (TWC: Front Catalyst) with the 2 bolts and 2 nuts.

   Torque: 55 N*m (561 kgf*cm, 41 ft.*lbf) 

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 front No. 3 exhaust pipe sub-assembly.
3. Using a plastic hammer and wooden block, tap in the exhaust pipe gasket until its surface is flush with the front No. 3 exhaust pipe sub-assembly.

   *1	Front No. 3 Exhaust Pipe Sub-assembly
   *2	Exhaust Pipe Gasket
   *a	Wooden Block

   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 center exhaust pipe assembly (TWC: Rear Catalyst) to the 4 exhaust pipe supports.
5. Install the center exhaust pipe assembly (TWC: Rear Catalyst) to the front No. 3 exhaust pipe sub-assembly with the 2 bolts and 2 compression springs.

   Torque: 43 N*m (438 kgf*cm, 32 ft.*lbf) 

   HINT: 

   After installation, check that the space between the flanges of the center exhaust pipe assembly (TWC: Rear Catalyst) and front No. 3 exhaust pipe sub-assembly is consistent front-to-rear and left-to-right.
