The Buick Riviera catalytic converter resides in an enlarged portion of your exhaust pipe. This mysterious and expensive-sounding part is actually just a filter, though the Riviera catalytic converter performs a very specialized function. The main purpose of your Buick Riviera catalytic converter is to convert harmful engine emissions into environmentally safe compounds such as nitrogen, water vapor, and carbon dioxide.

The honeycomb shaped Riviera catalytic converter accomplishes this through the use of small amounts of precious metals, usually palladium, platinum, and rhodium. When exhaust gases leave your cylinders through your exhaust manifold, they are carried through pipes to your Buick Riviera catalytic converter.

Once there, the metals embedded in the filter walls create a chemical reaction that smashes and re-forms the pollutant molecules, allowing only "safe" exhaust to escape through your tailpipe. There are several ways your Riviera catalytic converter can become damaged. If your oxygen sensor is not working properly, the excess fuel passing through your exhaust system as a result can damage your catalytic converter. Also, if you experience violent muffler problems such as your clamps letting go when you are driving, the subsequent damage to your muffler can also wreck your Riviera catalytic converter. Finally, since the catalytic converter is a filter, it will eventually wear out and lose effectiveness over time.
