Header Connection Pipes, Kooks, 2004-07 CTS-V, 3"

Kooks 3" connection pipes are made in the USA from the highest quality stainless steel on the market and are manufactured for use with Kooks headers. Available with High Flow Race Catalytic Converters with minimal flow restriction, Ultra High Performance GREEN Catalytic Converters with little to no flow restriction, or straight through pipes without catalytic converters, all connection pipes are designed to connect to the factory exhaust or mufflers. Kooks Headers and Exhaust EPA-Certified GREENCATS come with a 2-year limited replacement warranty. The standard High Flow Race Catalysts come with a 1-year limited replacement warranty. Vehicles equipped with a factory supercharger or turbocharger will only receive a warranty on Kooks Catalysts if they have the GREENCATS. There will be no warranty on our standard high flow catalyst if the vehicle comes equipped with a factory forced induction system. Furthermore, we recommend upgrading to the GREENCATS if your application will be producing more than 600 horsepower. GREENCATS can be installed on any of the Kooks exhaust systems.
