Your exhaust system – and
mufflers in particular
– is sophisticated, although you might not
appreciate how much so at a quick glance below your
car. Technically, your muffler has baffled passages
that the exhaust gases move through to muffle
engine noise. But if you were to cut away your
muffler, you’d find some tubes with holes in them.
Sounds simple, but inside your muffler, these
elements work together to have the sound waves
hit one another to reduce the noise. Your muffler
is actually a finely tuned instrument. |

Your
car's exhaust is crucial to its performance. While
the exhaust system is primarily designed to reduce noise,
it is also responsible for reducing harmful emissions. A properly functioning muffler and exhaust system not only sounds better, it is better for the environment. |

Your car exhaust system is pretty
complex.
Excess noise could be from cracks or holes in
manifolds or gaskets. Or on your muffler itself,
excessive rust on a muffler, on holes in a muffler
can cause a louder ride. Bad mufflers may also
lead to increased pollution and even a rough idle.
Decreased gas mileage and performance may also be a result of a poorly functioning exhaust system. |
