Catalytic converter replacement cost
for a Ford Focus

Replacing the catalytic converter on a Ford Focus involves removing the old unit, which is part of the exhaust system, and installing a new one to restore emissions control and engine performance. The cost is primarily driven by the price of the converter itself and the labour time, which varies significantly between standard and California-compliant parts and different model years.

Cost breakdown

Parts: ~$400-$1500 / Labour: ~$200-$400

What affects the price

Model year and engine type (e.g., 2.0L vs. 1.0L EcoBoost)
California Air Resources Board (CARB) compliant vs. federal/EPA compliant part
Whether replacing just the converter or the entire integrated exhaust manifold/catalytic assembly

Can you do it yourself?

Possible with skill — Requires safely lifting the car, penetrating rusted exhaust bolts, and potentially dealing with oxygen sensors. Specialized exhaust tools are recommended.

Tips before you pay

Verify if your state requires a CARB-compliant catalytic converter, as these are more expensive.
Consider having a professional diagnose to confirm the converter is faulty and not another sensor or engine issue.
After replacement, ensure the vehicle's readiness monitors reset and it passes an emissions test if required.
