Frequently Asked Questions

Are CATCO catalytic converters as good as OEM?

CATCO converters are designed to meet the same EPA and CARB emissions standards as OEM converters but at lower cost. They use quality substrates and proper precious metal loading. For most applications, they perform identically to OEM in terms of emissions compliance and check engine light prevention. They're an industry-leading aftermarket converter brand.

Does CATCO offer both CARB and EPA catalytic converters?

Yes, CATCO offers both CARB-compliant converters (required in California and CARB states) and EPA-certified converters (acceptable in all other states). They have extensive coverage for both certifications. Check product listings for the specific certification - CARB products have EO numbers listed.

How long do CATCO catalytic converters last?

CATCO converters typically last 100,000+ miles under normal conditions - comparable to OEM life expectancy. Premature failure usually indicates an upstream engine problem (misfires, oil burning, coolant contamination) that damages the catalyst. CATCO offers competitive warranty coverage for peace of mind.

Does CATCO make universal and direct-fit catalytic converters?

Yes, CATCO offers both. Direct-fit converters have vehicle-specific flanges and hangers for bolt-on installation. Universal converters are generic units requiring welding. Their direct-fit coverage is extensive for most popular vehicles. Use universals when a direct-fit isn't available for your application.

Will a CATCO converter cause a check engine light?

A properly functioning CATCO converter with correct application should not cause check engine lights. They're designed to meet emissions standards and keep O2 sensors happy. If you get P0420/P0430 codes after installation, double-check fitment, ensure O2 sensors are properly connected, and verify you don't have upstream engine issues.
