INSTALLATION
(1) Align and connect the exhaust pipe/catalytic converter to the muffler. Install exhaust clamp and tighten clamp nuts to 42 N*m (31 ft. lbs.) torque.
(2) Connect the exhaust pipe(s) to the exhaust manifold. Tighten the nuts to 34 N*m (25 ft. lbs.) torque.
(3) Connect oxygen sensor connector(s).
(4) Lower the vehicle.
(5) Start the engine and inspect for exhaust leaks and exhaust system contact with the body panels.
Adjust the alignment, if needed.
Catalytic converter
NOTE: Neither the inline catalytic converter nor the mini catalytic converters (California emission vehicles only) are serviceable separately from the exhaust pipe. Refer to Exhaust Pipe for removal / installation procedure.
