Kooks 3in H.O. Green Cats Catalytic Converter

Kooks Headers and Exhaust has been a leader in high-performance exhaust for over 50 years, known for crafting parts that win championships and set records. This 3-inch H.O. Green Cats catalytic converter carries that legacy, offering a way to reduce harmful emissions while maintaining excellent exhaust flow. It's built with a 300 CPSI high-flow substrate, designed to let your engine breathe easier, especially if you're running forced induction. This converter is certified to EPA standards, helping you meet emissions requirements.

This converter features a 3-inch inside diameter inlet and outlet, with a 4-1/2 inch outside diameter body that's 7 inches long overall. The stainless steel case is well-built for durability. Each unit is rated for up to 500 horsepower, making a pair suitable for systems up to 1000 horsepower. Kooks tests every product on the dyno and at the race track, ensuring it performs as expected. These are handcrafted in the USA by a family-owned company with three generations of experience.

Keep in mind that this converter is not CARB approved and cannot be shipped to California. While it's designed to help reduce emissions and is certified to EPA standards, the elimination of a check engine light is not guaranteed. If you're building a performance exhaust system and need a high-flow, EPA-certified catalytic converter, this is a solid option from a well-known name in the industry.
