WHAT’S THE DIFFERENCE BETWEEN THE STANDARD CAT AND THE KOOKS GREEN CAT?
These two cats are physically the same, and both use the same 300 cell high-flow substrate. The difference is in the coating that is applied to the substrate. The coating on the Kooks GREEN Cat has more of the precious metals required to create the proper reaction to function as a catalytic converter in newer vehicle exhaust systems. This coating also helps the cat withstand the increased heat in higher horsepower and forced induction applications. The standard cats carry a 1-year limited replacement warranty(No warranty if used in a forced induction application). The Kooks GREEN Cats carry a 2-year limited replacement warranty.
