CARB Compliant Catalytic Converters — California Approved Direct Fit

California Air Resources Board (CARB) Approved Catalytic Converters

Looking for a CARB compliant catalytic converter for your vehicle? You're in the right place. Restauco Parts specializes in CARB-approved direct fit catalytic converters that meet the strictest emissions standards in the United States — required for vehicles registered in California, New York, Colorado, and Maine.

Every CARB compliant catalytic converter we sell carries the CARB Executive Order (EO) number certifying it meets California Air Resources Board emission requirements. Installing a non-CARB converter in these states will result in failed smog inspections and potential fines.

Top CARB Compliant Brands We Carry

• Walker CalCat CARB Direct Fit — Industry-leading line designed specifically for CARB states. Direct OEM-style fitment with no modifications required.
• AP Exhaust CARB Direct Fit — Premium aftermarket option with extended warranty coverage on emissions components.
• CATCO Direct Fit and Universal CARB — Specialty manufacturer with hard-to-find SKUs for older or less common vehicles.
• Magnaflow CARB Compliant — High-flow performance option that retains CARB certification.

How to Choose the Right CARB Catalytic Converter

1. Confirm your state requires CARB — California, New York, Colorado, and Maine require CARB-compliant converters. Other states accept federal EPA converters.
2. Identify your vehicle Year, Make, Model, Engine size, and Submodel — Use the vehicle selector at the top of this page to find compatible converters automatically.
3. Choose Direct Fit over Universal when possible — Direct fit converters bolt in like the factory part. Universal converters require welding and exhaust modifications.
4. Verify the CARB Executive Order (EO) number — Every CARB converter has an EO number stamped on the body. Keep this for your smog inspection records.

Frequently Asked Questions

What is the difference between CARB and EPA catalytic converters?

EPA (Federal) catalytic converters meet basic emissions standards and are legal in 46 states. CARB converters meet the higher California Air Resources Board standards required for California, New York, Colorado, and Maine. CARB converters are always more expensive due to higher precious metal loading.

Will a CARB converter pass smog in any state?

Yes. A CARB-compliant converter automatically meets EPA standards as well, so it is legal in all 50 states. The opposite is not true — federal EPA converters fail in CARB states.

Do you ship catalytic converters nationwide?

Yes. We ship catalytic converters to all 50 US states. Shipping cost is calculated at checkout based on package dimensions and destination — most catalytic converters require oversized shipping due to their length (typically 40-60 inches).

What is your return policy on catalytic converters?

30-day returns on all unused, uninstalled catalytic converters. Visit our Returns page for full details.
