Fuel quality
Electrical connections
Intake air tube integrity
Fuses and relays
Is the check result normal?
Ye s>>Go to the next step.
No
>>Repair as necessary.

Description
The exhaust system provides an exit for exhaust gases and reduces engine noise by moving exhaust gases through
the three-way catalytic converter, a muffler inlet pipe and a muffler. Rubber exhaust hanger insulators attach the
exhaust system to the mounting hooks.
The exhaust system contains the following components:
•Catalytic converter assembly
• Muffler assembly
• Exhaust brackets with isolators bolted to the body
• Heated oxygen sensors mounted to the exhaust pipes
• Tailpipe assembly

Exhaust gases contain carbon monoxide which can be harmful to your health and are potentially lethal. Exhaust
system leaks should be repaired immediately. Never operate the engine in enclosed areas. Failure to follow
these instructions may result in personal injury or death.
Operation
In order to reduce vehicle emissions released by the engine, the catalytic converter is required to perform in all oper-
ating conditions. This reduction is especially beneficial during the cold start and warm up phases of operation, which
is when a majority of the tailpipe emissions occur on today’s vehicles because the catalytic converter has not yet
reached its operating temperature. The exhaust system channels exhaust gases from the engine and away from the
vehicle.
