How much is a new catalytic converter for a Ford Focus?

For a Ford Focus, a new catalytic converter generally costs between about $300 and $1,800 installed, depending on parts and labor. Parts alone typically range from roughly $150 to $1,200, with OEM units costing more than aftermarket replacements; labor adds to the total and varies by shop and region.

Several factors influence the final price, including the model year and engine, whether you choose an OEM Ford part or an aftermarket replacement, and whether the car uses one or multiple catalytic converters. Regional labor rates and any related work (sensors, gaskets, clamps) also affect the bottom line.

What determines the price

Prices hinge on the type of catalytic converter you buy, how many converters your Focus requires, and the overall service setup.

• OEM vs aftermarket parts: Ford-branded OEM converters fit exactly and may preserve warranty and emissions compliance but cost more; aftermarket direct-fit converters are usually cheaper but vary in fit and warranty.


• Number of catalytic converters: Some Ford Focus models use more than one converter; multiple units increase parts cost and labor.


• Engine year and configuration: Different engines and model years can use different designs, affecting both availability and price.


• Labor rates and location: Shop hourly rates and regional price differences can significantly influence total installed cost.


• Additional components and services: Oxygen sensors, clamps, gaskets, and any required exhaust work can add to parts and labor.


• Emissions compliance and warranty considerations: Ensuring the replacement meets local emissions standards and any applicable warranty terms is important.

Understanding these factors helps you estimate the cost and plan accordingly.

OEM vs aftermarket: Pros and cons

OEM parts are designed to match the original equipment exactly, which can help with emissions testing and warranties but often come at a premium. Aftermarket direct-fit parts are usually cheaper and can offer solid performance and warranties, but fit and consistency may vary between brands. Universal converters can save money but require more fabrication and may not be legal in all areas without proper installation and testing.

• Avoid legal and inspection issues: Many states require a working catalytic converter to pass emissions and smog tests for vehicle registration. Driving without one is illegal in most places. 
• Prevent engine damage: A malfunctioning or clogged converter can cause the engine to work harder, leading to sluggishness, misfires, and other issues. Continued driving can lead to more extensive and costly engine damage or failure. 
• Improve vehicle performance: A new converter will restore engine performance, improve acceleration, and can prevent other problems like stalling. 
• Increase fuel efficiency: A clogged converter can decrease your gas mileage, so replacement can improve your fuel economy. 
• Reduce harmful emissions: The primary function of a catalytic converter is to reduce harmful pollutants from your vehicle's exhaust, which is beneficial for the environment. 

When to consider replacement

• Signs of a problem: Look for symptoms like reduced engine power, a sulfur or rotten egg smell from the exhaust, poor acceleration, or a loud rattling noise from the exhaust system. The "check engine" light is often a sign of a failing catalytic converter, but it could also be triggered by other engine issues, so a proper diagnosis is important. 
• Cost vs. long-term cost: Even though replacement is expensive, the cost of ignoring the problem can lead to even more expensive engine repairs down the line. 
• Repair vs. replacement: If the catalytic converter is damaged, get an estimate for both repair and replacement. Often, replacement is the better option if the repair cost is similar to a new part.
