6K-2 EXHAUST SYSTEM
GENERAL DESCRIPTION
The exhaust system consists of an exhaust manifold, three-way catalytic converter (TWC) in catalyst case,
exhaust pipes, a muffler and seals, gasket and etc.
The three-way catalytic converter is an emission control device added to the exhaust system to lower the levels
of Hydrocarbon (HC), Carbon Monoxide (CO), and Oxides of Nitrogen (NOx) pollutants in the exhaust gas.
MAINTENANCE
At every interval of periodic maintenance service, and when vehi-
cle is raised for other service, check exhaust system as follows:
Check rubber mountings for damage, deterioration, and out
of position.
Check exhaust system for leakage, loose connection, dent
and damage.
If bolts or nuts are loosened, tighten them to specified
torque.
Refer to “GENERAL DESCRIPTION”.
Check nearby body areas damaged, missing, or misposi-
tioned part, open seam, hole connection or any other defect
which could permit exhaust fumes to seep into vehicle.
Make sure that exhaust system components have enough
clearance from underbody to avoid overheating and possible
damage to passenger compartment carpet.
Any defect should be fixed at once. WARNING:
To avoid the danger of being burned, do not touch the
exhaust system when the system is hot. Any service on
the exhaust system should be performed when the sys-
tem is cool.

EXHAUST MANIFOLD
REMOVAL AND INSTALLATION
Refer to Section 6A1 for removal and installation procedures of exhaust manifold.
INSPECTION
Check gasket and seal for deterioration or damage.
Replace them as necessary.
EXHAUST PIPE
REMOVAL AND INSTALLATION
For replacement of exhaust pipe, be sure to hoist vehicle and observe WARNING under “MAINTENANCE” and
the following.
Tighten bolts and nuts to specified torque when reassembling. Refer to “GENERAL DESCRIPTION” for
location of bolts and nuts.
After installation, start engine and check each joint of exhaust system for leakage. CAUTION:
Exhaust pipe have three way catalytic converter in it, it should not be exposed to any impulse.
Be careful not to drop it or hit it against something.
