About Chevrolet Impala Catalytic Converter

The Chevrolet Impala is now in its tenth generation. The brand is well-known for its nice and great parts. Classic parts such as the catalytic converter contribute to the success of the Chevrolet Impala. Many modern cars have a catalytic converter that has a honeycomb interior. While older cars have a ceramic beads design. The purpose of the design is to slow down the speed at which the exhaust gases are traveling. When Chevrolet Impala catalytic converter was introduced, it was accompanied by a carburetor which provided a rich ratio of air and fuel.
Although Chevrolet Impala has a lot of nice and great car parts, the catalytic converter still needs repair after a long time of usage. Signs of a bad catalytic converter include poor engine performance, black exhaust smoke, a bad smell from the exhaust, and the check engine light on the dashboard. The removal process of the Chevrolet Impala catalytic converter is as follows. Disconnect the upstream and downstream sensors first. Next, get rid of the nuts from the flanges connecting them to the rest of the exhausts. Then get rid of old exhaust gaskets. In the end, disconnect exhaust hangers, if needed. Choose from a lot of nice and great Chevrolet Impala catalytic converter parts at varied prices online. We have most of the classic parts.
