INSTALL FRONT EXHAUST PIPE ASSEMBLY (TWC: Rear Catalyst)

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

Standard Length	40 mm (1.57 in.)
Minimum Free Length	38.5 mm (1.52 in.)

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

Temporarily install 2 new gaskets to the front exhaust pipe assembly (TWC: Rear Catalyst) for tail exhaust pipe assembly and tail exhaust pipe LH side.

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

NOTE:

Be sure to install the gaskets in the correct direction.
Do not reuse the gaskets.
Do not damage the gaskets.
Do not push in the gaskets by using the front exhaust pipe assembly (TWC: Rear Catalyst) when connecting it.
