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 the RH upper catalytic converter-to-exhaust manifold nut.
^ Tighten the transmission mount hanger bolt.
^ Tighten the exhaust clamp nut.
^ Alternately tighten the LH catalytic converter-to-exhaust manifold nuts, to avoid an exhaust leak.
Install and snug the LH inner nut up.
Tighten the LH outer nut to specification.
