Frequently Asked Questions

What does CalCat mean?

CalCat stands for "California Catalytic" - the line name Walker uses for its CARB-compliant catalytic converters specifically designed to meet California Air Resources Board emission standards.

Will a Walker CalCat fit my non-CARB state vehicle?

Yes. CalCat converters meet both CARB and EPA standards, so they are legal in all 50 states. However, if you live in a non-CARB state, you may save money by choosing a Walker EPA-only converter.

Walker CalCat catalytic converters are engineered to last 100,000+ miles under normal driving conditions, similar to the original equipment converter. Premature failure usually indicates an underlying engine problem (oil burning, rich fuel mixture, or misfires).
