Exhaust System Description
Important
Use
of
non-OEM parts
may
cause driveabiiity concerns.
The exhaust system design varies according to the model designation and the intended use
of
the
vehicle.
In
order to secure the exhaust pipe to the exhaust manifold, the exhaust system utilizes a flange and seal
joint coupling. A flange and gasket coupling secures the catalytic converter assembly to the muffler
assembly.
Hangers suspend the exhaust system from the underbody, allowing some movement
of
the exhaust
system and
disallowing the transfer
of
noise and vibration into the vehicle.
Heat shields protect the vehicle from the high temperatures generated
by
the exhaust system.
Resonator
Some exhaust systems are equipped with a resonator. The resonator, located either before
or
after the
muffler, allows the use
of
mufflers with less back pressure. Resonators are used when vehicle
characteristics require specific exhaust tuning.
Catalytic Converter
The catalytic converter is an emission control device added to the engine exhaust system
in
order to
reduce hydrocarbons (HC), carbon monoxide (CO), and oxides
of
nitrogen (NOx) pollutants from the
exhaust gas.
The catalytic converter is comprised
of
a ceramic monolith substrate, supported
in
insulation and housed
within a sheet metal shell. The substrate may be washcoated
with3
noble metals:
• Platium
(Pt)
• Palladium (Pd)
• Rhodium (Rh)
The catalyst
in
the converter is not serviceable.
