INSTALL FRONT EXHAUST PIPE ASSEMBLY (TWC: Rear Catalyst)
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.
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 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 pipe when connecting it.
Connect the front exhaust pipe assembly (TWC: Rear Catalyst) to the exhaust pipe support.
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.
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.

| *2 | Front Exhaust Pipe Assembly (TWC: Rear Catalyst) |
| *3 | Exhaust Pipe Gasket |
| *a | Space between Flanges: 8.5 mm (0.335 in.) |
INSTALL CENTER EXHAUST PIPE ASSEMBLY
Install a new exhaust pipe gasket to the front exhaust pipe assembly (TWC: Rear Catalyst).
Connect the center exhaust pipe assembly to the exhaust pipe support.
Install the center exhaust pipe assembly to the front exhaust pipe assembly (TWC: Rear Catalyst) with the 2 nuts.
INSTALL TAIL EXHAUST PIPE ASSEMBLY
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.
Temporarily install a new exhaust pipe gasket to the center exhaust pipe assembly.
| *1 | Center Exhaust Pipe Assembly |
| *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.
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.
Connect the tail exhaust pipe assembly to the 3 exhaust pipe supports.
Install the tail exhaust pipe assembly to the center exhaust pipe assembly 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 and tail exhaust pipe assembly is consistent front-to-rear and left-to-right.
| *1 | Tail Exhaust Pipe Assembly |
| *2 | Center Exhaust Pipe Assembly |
| *3 | Exhaust Pipe Gasket |
| *a | Space between Flanges: 6.5 mm (0.256 in.) |
INSTALL HEATED OXYGEN SENSOR
| *a | Torque Wrench Fulcrum Length |
Using SST, install the heated oxygen sensor to the front exhaust pipe assembly.
Note
If the heated oxygen sensor has been struck or dropped, replace it.
Tech Tips

When using SST (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 260 mm (10.2 in.)): 39 N*m (398 kgf*cm, 29 ft.*lbf)
Connect the heated oxygen sensor connector.
INSPECT FOR EXHAUST GAS LEAK
If gas is leaking, tighten the areas necessary to stop the leak. Replace damaged parts as necessary.
