PROCEDURE
INSTALL FRONT EXHAUST PIPE ASSEMBLY
Using a vernier caliper, measure the free length of the compression spring.
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.
Temporarily install a new exhaust pipe gasket to the exhaust manifold converter sub-assembly (TWC: Front Catalyst).
*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 sure to install the exhaust pipe gasket in the correct direction.
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.
Install the front exhaust pipe assembly to the exhaust manifold converter sub-assembly (TWC: Front Catalyst) with the 2 compression springs and 2 bolts.
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.

*2 | Front Exhaust Pipe Assembly |
*3 | Exhaust Pipe Gasket |
*a | Space between Flanges: 9.5 mm (0.374 in.) |
INSTALL CENTER EXHAUST PIPE ASSEMBLY (TWC: Rear Catalyst)
Install a new exhaust pipe gasket to the front exhaust pipe assembly.
Connect the center exhaust pipe assembly (TWC: Rear Catalyst) to the 2 exhaust pipe supports.
Install the center exhaust pipe assembly (TWC: Rear Catalyst) to the front exhaust pipe assembly with the 2 nuts.
INSTALL TAIL EXHAUST PIPE ASSEMBLY
Using a vernier caliper, measure the free length of the compression spring.
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.
Temporarily install a new exhaust pipe gasket to the center exhaust pipe assembly (TWC: Rear Catalyst).
*1 | Center Exhaust Pipe Assembly (TWC: Rear 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 center exhaust pipe assembly (TWC: Rear Catalyst).
Note
Be sure to install the exhaust pipe gasket in the correct direction.
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.
Connect the tail exhaust pipe assembly to the 2 exhaust pipe supports.
*1 | Center Exhaust Pipe Assembly (TWC: Rear Catalyst) |
*2 | Tail Exhaust Pipe Assembly |
*3 | Exhaust Pipe Gasket |
*a | Space between Flanges: 9.5 mm (0.374 in.) |
Install the tail exhaust pipe assembly to the center exhaust pipe assembly (TWC: Rear Catalyst) with the 2 compression springs and 2 bolts.
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.
INSTALL NO. 2 TAIL EXHAUST PIPE ASSEMBLY
Connect the tail exhaust pipe assembly to the 2 exhaust pipe supports.
Install the No. 2 tail exhaust pipe assembly to the tail exhaust pipe assembly with the 2 bolts.
INSTALL EXHAUST PIPE DAMPER
Install the exhaust pipe damper to the tail exhaust pipe assembly with the 2 bolts.
INSTALL HEATED OXYGEN SENSOR
INSPECT FOR EXHAUST GAS LEAK
If gas is leaking, tighten the areas necessary to stop the leak. Replace damaged parts as necessary.
Perform Inspection After Repair after repairing an exhaust gas leak.
