*a	Wooden Block

Using a plastic hammer and wooden block, tap in the gasket until its surface is flush with the exhaust manifold converter sub-assembly (TWC: Front Catalyst).

NOTICE:

·

Be sure to install the gasket in the correct direction.

·

Do not reuse the gasket.

·

Do not damage the gasket.

·

Do not push in the gasket by using the exhaust pipes when connecting them.

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.
