1. With the vehicle in NEUTRAL, position it on a hoist.
2. Loosen all exhaust component fasteners and clamps from the exhaust manifolds to the muffler inlet pipe.

3. NOTE: Make sure the exhaust isolators are not torn, damaged or binding.

Beginning at the front of the vehicle, align the exhaust system to establish the maximum clearance. Make sure that all slip fit pipes are pushed all the way into the preceding pipe and the notches are correctly lined up with the tabs.

Tighten all the fasteners in the following order:
^ Tighten the RH lower catalytic converter-to-exhaust manifold nut.

^ Tighten the exhaust clamp nut.
^ Tighten the LH outer catalytic converter-to-exhaust manifold nut.
