Catalytic Converters - Presented by Andy's Auto Sport: This is an Andy's Auto Sport TV episode where we break down the basics of catalytic converters. We explain the difference between a direct-fit bolt-on catalytic converter and a universal weld-on catalytic converter. We also go over the benefits of getting a new cat, and we even do an installation to show what's involved.
