In the United States, replacing a catalytic converter on a Subaru typically costs about $900 to $2,500 for a single converter, and $1,400 to $3,500 if the model has two converters, depending on model and parts.
Costs vary by model, number of converters, whether you choose OEM or aftermarket parts, and local labor rates. Environmental and emissions standards can influence part choice and final pricing, and more complex exhaust systems or rust can push the total higher.
What affects the cost
Several factors influence the final price you see on a repair bill. The list below highlights the main variables drivers of cost.
- Number and arrangement of catalytic converters on your Subaru (some engines use one converter, others use two or more).
- Parts choice: OEM (dealer) parts generally cost more than aftermarket or high-flow alternatives, with aftermarket options offering a balance of cost and performance.
- Labor rates and shop location: urban areas and dealerships typically charge more per hour than independent shops or rural shops.
- Condition of the exhaust system and surrounding hardware: rusted bolts, damaged hangers, or a clogged pre-cat can add labor time or require extra parts.
- Emissions and inspection requirements: some states require CARB-compliant parts for repairs on newer Subarus.
- Additional work: replacing downstream oxygen sensors, gaskets, or fixing leaks may add to the total.
Understanding these factors can help you get a fair quote and avoid surprises when the shop completes the repair.
Typical price ranges by configuration
Prices vary by how many catalysts your Subaru has and whether you use OEM or aftermarket parts. The ranges below reflect typical figures seen in the U.S. market as of 2024–2025.
- Subaru with a single catalytic converter: 900–1,800 total (parts and labor).
- Subaru with two catalytic converters: 1,400–3,500 total (parts and labor).
- Parts choice impact: aftermarket converters generally cost less upfront than OEM; expect OEM hardware to be at the higher end of the range, while aftermarket can reduce cost but may affect warranty or emissions compliance in some areas. Typical per-unit parts pricing can range from about 150–700 for aftermarket to 600–1,300 for OEM, with labor approximately 100–200 per hour depending on location.
These figures are broad estimates; exact pricing depends on the exact model, part quality, and labor rates at the repair shop.
What to expect during replacement
Before performing the work, a shop will typically diagnose the problem, confirm the catalytic converter needs replacement, and provide a written quote. The replacement process can vary in duration but generally follows these steps.
- Diagnosis and quote based on diagnostic codes and inspection.
- Removal of old catalytic converter(s) and any corroded hardware.
- Installation of the new converter(s) and replacement of gaskets or sensors as needed.
- Leak checks, exhaust system inspection, and sensor readiness checks.
- Reassembly and test drive to confirm proper operation.
- Emissions readiness or inspection updates, depending on local requirements.
Be aware that rust, seized bolts, or damaged exhaust components can extend the time and cost of the replacement.
Ways to save on a catalytic converter replacement
Consider these practical steps to minimize costs while ensuring a quality repair.
- Get multiple quotes from reputable shops, including dealership and independent mechanics.
- Ask about aftermarket versus OEM options and confirm CARB compliance if you live in a state with strict emissions rules.
- Check for warranties or guarantees on the converter and labor.
- Plan for possible additional work if your exhaust system shows signs of wear or rust.
By comparing options and understanding the scope of work, you can secure a fair price while maintaining vehicle emissions compliance.
Summary
Replacing a catalytic converter on a Subaru is a common but potentially costly repair, driven mainly by the model (single vs dual converter), parts choice, and local labor rates. Expect roughly 900–1,800 for a single converter and 1,400–3,500 for two, with OEM parts generally costing more than aftermarket. Always obtain multiple quotes, confirm emissions compliance, and be prepared for possible additional repairs if the exhaust system shows wear. For an exact figure, check with a local shop for your specific Subaru model and location.
