Catalytic converter replacement cost
for a Subaru Outback

Replacing the catalytic converter on a Subaru Outback involves removing the old, failed unit from the exhaust system and installing a new one. The cost is primarily driven by the high price of the converter itself, which contains precious metals, and the labour required to access it, which can vary significantly by model year and engine.

Cost breakdown

Parts: ~$800-$2000 / Labour: ~$400-$800

What affects the price

Model year and engine (e.g., 6-cylinder vs 4-cylinder, emissions standards)
OEM vs. aftermarket or universal 'direct-fit' converter
Whether one or both converters need replacement (some models have two)

Can you do it yourself?

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

Tips before you pay

Ensure the replacement converter meets your state or country's emissions regulations for legal compliance.
Diagnose the root cause of failure (e.g., engine misfire) before replacement to prevent damaging the new one.
Consider the condition of related exhaust components like gaskets and oxygen sensors while the system is apart.
