Kooks Universal 3 Inch ULTRA-GREEN Catalyst 3in Inlet/3in Outlet/4in Long/4.5in OD Body/7In OAL

If you're building a custom exhaust system or replacing a damaged catalytic converter, this Kooks ULTRA-GREEN unit is a solid choice for managing emissions. It's designed to handle significant exhaust flow, making it suitable for modified vehicles, including those with forced induction setups. This converter helps reduce harmful emissions and is certified to meet EPA standards.

This converter features a 3-inch inlet and outlet, with a 4-inch long body and a 4.5-inch outer diameter, giving it an overall length of 7 inches. Inside, it uses a 400 cell per square inch (CPSI) high-flow substrate. This design allows for better exhaust gas flow compared to standard converters, which can help maintain performance. Kooks rates this converter for up to 425 horsepower per unit, or 850 horsepower if you use a pair.

Kooks has been making performance exhaust components for over 50 years, and this catalytic converter is handcrafted in the USA from T304 aircraft-quality steel. It comes with a limited lifetime warranty to the original purchaser. Please note that this converter is not CARB approved and cannot be shipped to California. While it's designed to help prevent a check engine light, elimination of the light is not guaranteed.
