What does it cost to replace a Catalytic Converter
The catalytic converter as a general rule of thumb is the most expensive piece of a vehicle's exhaust system. The price to replace a catalytic converter often depends on which one on the vehicle needs to be replaced. Four cylinder vehicles typically have 1-2 catalytic converters. Six and 8 cylinder vehicles typically have 4-5 catalytic converters. The front positioned catalytic are almost always read by the oxygen sensors and will also sometimes come as an assembly with the exhaust manifold generating a high cost of replacement. A general range for a catalytic converter based on these factors ranges from $500-$2,500.
How does the Catalytic Converter work?
The catalytic converter main purpose is to control harmful emissoins that engines produce. It is a device that breaks down and converts toxic, harmful gases and pollutants (carbon monoxide, nitrogen oxides, and other hydrocarbons), cutting down emissions and reducing smog. On the inside of the Catalytic Converter pipe on the entry and exit, there is a ceramic honeycomb screen that contains metals such as platinum, palladium, and rhodium. These elements help to clean the a vehicle's gases and emissions so when it comes out of the tailpipe, it is less harmful to the environment.
When the catalytic converter is not performing as well as it needs to according to the vehicle specifications, it will trigger a check engine light.
Based on catalytic converter malfunction, you might fail a state mandated emissions test.
As a catalytic converter gets very clogged or excessively dirty, it can cause a loss of power and hurt gas mileage based on the inability to move the engine's emissions out of the exhaust system.
If your exhaust smells like sulfur or rotten eggs, it could be a converter that isn’t doing its job. Dark smoke indicates unburned fuel or contaminants.

How urgent are Catalytic Converter repairs?
A catalytic converter that is not performing as it should normally indicates secondary problems with how the car is running. If the air/fuel ratio is not correct, or the spark plugs or ignition coils are faulty, it can cause a misfire condition or cause the car to run poorly. This is one of the most common attributing factors to what causes a catalytic converter to underperform and fail. If it fails and the inner screens break, this can cause back pressure to the engine which can harm the engine, and it can cause a lack of power while driving. Because of these things as well as producing harmful emissions if a catalytic converter is not working, you should repair it as soon as possible.
