PROCEDURE
1. INSTALL FRONT EXHAUST PIPE ASSEMBLY (TWC: Rear Catalyst)
.png)
|
*1 | Exhaust Manifold (TWC: Front Catalyst) |
*2 | Gasket |
|
*a | Wooden Block |
*b | Plastic Hammer |
(1) Using a vernier caliper, measure the free length of the compression springs.
|
Standard Length | 43 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 gasket to the exhaust manifold (TWC: Front Catalyst).
(3) Using a plastic hammer and wooden block, tap in the gasket until its surface is flush with the exhaust manifold (TWC: Front Catalyst).
NOTICE:
- 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.

*1 | Exhaust Manifold (TWC: Front Catalyst) |
*2 | Front Exhaust Pipe Assembly (TWC: Rear Catalyst) |
|
*3 | Gasket |
- | - |
|
*a | Space between Flanges: 8.5 mm (0.335 in.) |
- | - |
(1) Connect the front exhaust pipe assembly (TWC: Rear Catalyst) to the 2 exhaust pipe supports.
(2) 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}
(3) After installation, check that the space between the flanges of the exhaust manifold and front exhaust pipe assembly is consistent front-to-rear and left-to-right.

|
*a | Space between Flanges: 6.5 mm (0.256 in.) |
- | - |
(1) Connect the tail exhaust pipe assembly to the 3 exhaust pipe supports.
(2) Install the tail exhaust pipe assembly to the front exhaust pipe assembly (TWC: Rear Catalyst) with the 2 compression springs and 2 bolts.
Torque:
43 N·m {438 kgf·cm, 32 ft·lbf}
(3) 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.
