A catalytic converter for a 2003 Subaru Forester typically costs roughly $100–$300 for an aftermarket single-cat, $400–$800 for an OEM single-cat, and if the vehicle has two converters, about $200–$600 for aftermarket for both or $800–$1,800 for OEM for both. Labor and installation are extra. Availability and prices can vary by region and emissions requirements (CARB-compliant units may be pricier).
What affects price
Prices vary based on whether you need one or two converters, whether you choose aftermarket or OEM, and regional emissions rules. The following ranges reflect common market prices as of 2024–2026.
- One catalytic converter (single-cat) options:
- Aftermarket: about $100–$300
- OEM: about $400–$800
- Two catalytic converters (dual-cat) options:
- Aftermarket (both units): about $200–$600
- OEM (both units): about $800–$1,800
Prices vary by brand, exact model variant, and whether the unit is CARB-compliant. Verify the exact fitment for the Forester’s engine and emission requirements before purchasing.
Labor and installation costs
Install costs can significantly affect total price. The following breakdown covers typical scenarios you may encounter.
- Labor and installation:
- Typical labor costs: $70–$150 per hour
- Total labor estimate: roughly $100–$450, depending on shop rates and time required
- Other costs to consider:
- Gaskets, clamps, and oxygen sensor work: $10–$300 depending on what's needed
- Diagnostics or warranty considerations
- Where to buy and what to expect:
- Reputable auto parts retailers and auto salvage yards can vary widely in price; online retailers may offer lower base prices but check shipping and returns; ensure a CARB-compliant unit if you’re in California or other CARB states
In short, labor and ancillary costs can add a sizable amount to the part price, so obtaining multiple quotes is wise and ensure compatibility with your Forester’s emissions requirements.
Summary
For a 2003 Subaru Forester, expect the catalytic converter price to range from about $100 to $1,800 for the converter(s) alone—lower if you opt for aftermarket single-cat units and higher for OEM dual-cat configurations. Add roughly $100–$450 for labor and installation, plus minor parts like gaskets and clamps. Always confirm whether your vehicle requires one or two converters and whether a CARB-compliant unit is necessary in your state, and shop with reputable suppliers or service centers to ensure proper fit and warranty coverage.
