Catalytic Converters

What does a performance catalytic converter do?

A high flow catalytic converter, or high flow cat, allows exhaust gases to flow through the system at a higher rate with less restriction. This efficiency gain can improve horsepower and fuel economy.

Are high flow cats illegal?

Accesspeed offers high flow catalytic converters that in both 49-state and CARB-approved 50-state configurations. Federal and state emissions laws are crystal clear on what you can and cannot do with regard to replacing catalytic converters.
