Product Questions & Answers
Shopping for Catalytic Converter
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.
