PROCEDURE

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

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

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) 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.

3. INSTALL TAIL EXHAUST PIPE ASSEMBLY

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

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

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

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