Mufflers & Exhaust System

The exhaust system is an
essential component of your
motor vehicle. Firstly, the
exhaust helps to direct
noxious gases away from the
cabin, so you will not be
exposed to the harmful gases that can
cause immediate and long
term health issues.
Another important function
of the exhaust is to make
sure your car is being as
fuel efficient as possible,
by monitoring the levels of
oxygen emitted and using
this information to balance
the fuel/air mix of the
engine to the optimum level.
Reasons for Exhaust Failure
Your vehicles exhaust
system is located beneath
the
motor vehicle and is subject
to damage from stones, dirt,
water and other road
hazards.
Internally extreme
temperature changes together
with a mixture of combustion
gases and moisture, cause
formation of acids that eat
into internal metal
surfaces. This corrosion is
evident in the form of rust
pin holes or cracks.
Warning Signs of a Faulty
Exhaust System or Muffler
-
When your vehicle makes a
louder noise than usual.
-
When fuel consumption
increases or lack of
performance is noted.
-
When rust is visible on
exhaust system parts.
-
When rattles are evident
from the exhaust system.
-
When holes and cracks
appear and exhaust gases
leak.
Danger Signs You Should
Look Out For
When the smell of fuel or
oil odours no matter how
slight, are detected within
the passenger compartment.
The system could be leaking
and lethal carbon monoxide
levels building up.
Reasons for Maintaining
Exhausts
Your exhaust system performs
several extremely important
jobs.
It takes exhaust gases from
the engine to the rear of
the vehicle, keeping
dangerous fumes away from
the occupants.
It also keeps engine noise
to comfortable levels inside
and outside the vehicle.
Exhaust systems are made up
of a variety of components,
custom designed to fit
individual vehicles using
pipes and mufflers which
maintain correct back
pressure.
This in turn enables optimum
engine power with minimum
fuel consumption.
The Single Biggest Cause of
Exhaust System Failure
Rust is the biggest cause
exhaust system failure and it usually works from
the inside out. A mixture of
water and sulphuric acid in
exhaust gases, corrode pipes
and the internal baffling of
the muffler barrel.
Vehicles used for short
journeys, tend to corrode
their exhaust systems more
quickly. In this case, the
muffler does not reach high
enough temperatures to 'dry
out', leaving the water and
acid to accelerate the
rusting process.
The complete system is
particularly susceptible to
damage and wear from the
outside environment.
Underneath the vehicle, it
is exposed to stones, dirt,
water, spills and other road
hazards. It really does have
a tough life. A failing
exhaust system will affect
your vehicle's performance.
