WARNING: THE NORMAL OPERATING TEMPERATURE OF THE EXHAUST SYSTEM IS VERY HIGH. THERE-
FORE, 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 CONVERTER RISES TO A HIGH LEVEL AFTER A SHORT PERIOD OF ENGINE
OPERATION TIME.

CAUTION: Avoid application of rust prevention compounds or undercoating materials to exhaust system
floor pan heat shields. Light overspray near the edges is permitted. Application of coating will result in
excessive floor pan temperatures and objectionable fumes.

The 3.7L/4.7L exhaust system uses two catalytic converters located in the front exhaust pipe, and a single muffler/
tailpipe assembly.

EXHAUST SYSTEM

The 5.7L exhaust system uses two catalytic converters located in the front exhaust pipe, and a single muffler and
tailpipe/resonator assembly.

The front exhaust pipe/catalytic converter assembly is a hydra-form thin wall air gap design. This design is used to
reduce heat, noise and improve emissions. When replacement is required, use original equipment parts (or their
equivalent).

The exhaust manifolds are equipped with ball flange outlets to assure a tight seal and strain free connections.

The exhaust system must be properly aligned to prevent stress, leakage and body contact. If the system contacts
any body panel, it may amplify objectionable noises originating from the engine or body.

When inspecting an exhaust system, critically inspect for cracked or loose joints, stripped screw or bolt threads,
corrosion damage and worn, cracked or broken hangers. Replace all components that are badly corroded or dam-
aged. DO NOT attempt to repair.

When replacement is required, use original equipment parts (or their equivalent). This will assure proper alignment
and provide acceptable exhaust noise levels.

The basic exhaust system consists of exhaust manifold(s), exhaust pipe with oxygen sensors, catalytic converter(s),
muffler and tailpipe.
