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.
PURCHASE A GREEN CAT, A TREE IS PLANTED
Kooks has teamed up with OneTreePlanted, an environmental charity focused on global reforestation. For every GREEN cat purchase from Kooks, a tree will be planted in California, Oregon & Appalachia.
OneTreePlanted is a 501(C)(3) non-profit organization that is dedicated to helping the environment by planting trees worldwide with the help of individuals and businesses to create a healthier climate, protect biodiversity and helping reforestation efforts. With each tree that is planted, it helps to restore forests after fires and floods, it creates jobs and builds communities on a global level and it helps protect natural habitats for biodiversity. Just in 2019 alone, over 4 million trees were planted worldwide!
