Catalytic Converters

Don’t take an emissions test until you’ve replaced a bad catalytic converter. Residue from exhaust gases can build up in the catalytic converter over time, resulting in increased emissions that will definitely register during the test. If your catalytic converter is clogged or otherwise in bad shape, replace it immediately. Good thing CarParts.com has a wide range of catalytic converters made by top manufacturers in the industry. Take a look at our products today and choose one that matches your application.

How Much Does a Catalytic Converter Replacement Cost?

A typical catalytic converter’s cost can range from $50 to $1000 on parts alone. Prices vary depending on the brand and the specifications of your vehicle’s cat-con. Labor costs may also differ significantly between different makes and models because the amount of time it takes to install the part may vary per vehicle. Expect to spend around $70 to $130 per hour on labor. You’ll also have to factor in other expenses for related repairs.

What Is a Catalytic Converter?

A catalytic converter (or cat for short) is a critical part of your engine’s exhaust system. This device converts the harmful chemicals in the exhaust using catalysts.

Most modern models look like passageways of closely formed mesh made of honeycomb interior. Older car models are different because they feature ceramic beads instead of a honeycomb design. Their purpose is to slow down the flow of exhaust gases through the converter, allowing more time for the catalysts to interact with the emission gases.
