Exhaust System Components
Over the last 10 years or so, the
use of aluminized and stainless steel for exhaust
pipes has increased substantially. As you might
think, the use of these materials has significantly
increased the service life of the exhaust
system.
However exhaust work is still done, albeit not to
the extent it was in the past. For those times when
exhaust work is required, let's take a look at how
to inspect and replace exhaust system
components.

The Basic Exhaust System
Most vehicles have a single
exhaust system which includes a catalytic
converter, a long length of pipe and a muffler.
this long length of pipe can be fitted over a
section of pipe extending from the converter and
fitted into a section of pipe welded to the
muffler.
On
V-engines, there will be a crossover pipe, formed
from exhaust pipes from each exhaust manifold that
are welded together to make a single pipe.
There are probably several metal hangers, welded to
the pipe, that are inserted into rubber isolators
to support the exhaust system. Finally, don't
forget that the downstream oxygen sensor is
installed in the catalytic converter.
