A Chevy Impala Exhaust System starts with the "header," or exhaust manifold (so-called because of it's curious resemblance to a human hand). A passenger car typically contains a "collector," which literally "collects" exhaust gases before sending them on to the exhaust pipe by way of the catalytic converter and muffler. While in the catalytic converter, these gases - deadly carbon monoxide and nitrous oxide - are broken and recombined at the molecular level into relatively harmless CO2 and water vapor.

Finally, the exhaust gas travels through the muffler, where the eardrum-shattering racket of thousands of cylinder explosions per minute is "muffled" to a low rumble before exiting through the tailpipe. Any of these components are subject to wear and tear throughout the lifetime of your vehicle, or may be damaged.

A leak in the exhaust manifold can compromise engine performance, while raw gasoline burning in the catalytic converter can melt the interior components, clogging the system. A defective muffler will make your car sound like automatic weapon fire, and put it in violation of many local noise ordinances. Alternatively, you may wish to replace some of the stock components of your Chevy Impala Exhaust System with custom performance ones - such as a custom header or an X-pipe, both of which increase engine performance significantly.
