The exhaust system on
your vehicle has three main functions.
1. It transfers poisonous
exhaust gases from the engine to the rear of the
vehicle.
2. It quietens the sound of
the engine while running.
3. It converts unspent fuel
into spent fuel.
The main exhaust system
components are: Exhaust manifold, Exhaust pipe,
Catalytic converter, silencer, tail pipe, EGR
valve, NOX & O2
sensor/s.
Exhaust system components
commonly fail due to corrosion over time,
although, the catalytic converter (one of
the most expensive parts in the exhaust
system) can be easily damaged if the engine
is not running efficiently due to common
engine management faults, such as faulty
oxygen sensor/s or engine misfire etc.
