CROSS-UNDER PIPE - 2.7L (Continued)
(7) Reconnect downstream oxygen sensor connec-
tors.
(8) Lower vehicle.
(9) Start the engine and inspect for exhaust leaks.
Repair exhaust leaks as necessary.
(10) Check the exhaust system for contact with the
body panels. Make the necessary ajustments, if
needed.

REMOVAL
NOTE: In the following procedure it is not neces-
sary to separate the muffler/pipe assembly from the
resonator/pipe
assembly.
removed as an assembly.
WARNING: THE NORMAL OPERATING TEMPERA-
TURE OF THE EXHAUST SYSTEM IS VERY HIGH.
THEREFORE, NEVER WORK AROUND OR ATTEMPT
TO SERVICE ANY PART OF THE EXHAUST SYSTEM
UNTIL IT IS COOLED. SPECIAL CARE SHOULD BE
TAKEN WHEN WORKING NEAR THE CATALYTIC
CONVERTER. THE TEMPERATURE OF THE CON-
VERTER RISES TO A HIGH LEVEL AFTER A SHORT
PERIOD OF ENGINE OPERATION TIME.
(1) Raise vehicle on hoist and apply penetrating oil
to resonator/pipe assembly band clamp, and the fas-
teners that connect the exhaust system to the cross-
under pipe (Fig. 1).
(2) Remove ground strap from muffler.
(3) Loosen band clamp for resonator/pipe assembly.
CAUTION: Do not use any tools to remove the rub-
ber isolators–remove by hand only. Soapy water or
silicone–based lubricant spray may be used to
assist removal/installation of isolators. DO NOT use
a petroleum–based lubricant on the isolators, as
damage to the rubber material can occur.
(4) Remove support isolators from muffler sup-
ports.
(5) Remove resonator/pipe and muffler/pipe as an
assembly.
(6) Remove fasteners that attach exhaust pipe to
cross-under pipe.
(7) Remove exhaust pipe.

INSTALLATION
NOTE: Always work from the front to rear of
exhaust system when aligning and tightening
exhaust system components.
(1) Loosely attach exhaust pipe to cross-under
pipe.
(2) Loosely install resonator/pipe and muffler/pipe
assembly to exhaust pipe.
(3) Install support isolators to muffler supports.
(4) Align exhaust pipe and resonator/muffler pipe
assembly to maintain position and proper clearance
with underbody parts. All support isolators should
have equal load on them. Tighten fasteners attaching
exhaust pipe to cross-under pipe to 28 N·m (250 in.
lbs.).
(5) Tighten resonator/pipe assembly band clamp to
54 N·m (40 ft. lbs.).
(6) Connect ground strap to muffler.
(7) Lower vehicle.
(8) Start the engine and inspect for exhaust leaks.
Repair exhaust leaks as necessary.
(9) Check the exhaust system for contact with the
body panels. Make the necessary ajustments, if
needed.
