Kooks Headers Header and High Output GREEN Catted Connection Kits

Kooks Headers Header and High Output GREEN Catted Connection Kits are performance exhaust upgrades for a vehicle, consisting of long-tube exhaust headers and high-output, EPA-verified catalytic converters (the "GREEN Cats") integrated into a connection pipe. They are application-specific, designed for a particular vehicle model and year—and are engineered to improve engine power, torque, and sound by allowing the engine to "breathe" more easily, while still meeting emissions standards. The "GREEN" designation refers to the specific type of high performance catalytic converter with a lower 400 CPSI substrate, making it suitable for high-horsepower applications. Kits are available with 1 7/8 in. or 2 in. primary tube outside diameter.

Key components and features:

* Headers: These are long, mandrel-bent tubes made from 304 stainless steel that replace the restrictive factory exhaust manifolds.
* High-Output GREEN Catted Connection Pipes: These are the pipes that connect to the headers and feature Kooks' Ultra High Performance GREEN Cats.
* High-Output GREEN Cats: These are high-flow catalytic converters designed to reduce emissions while handling high horsepower levels.
* Installation Hardware: The kit includes all necessary gaskets, clamps, and hardware, and in some cases, oxygen sensor extension harnesses, for a complete installation.
* OEM Connection Point: The connection pipes are designed to bolt up to the vehicle's factory exhaust system.
* Application-Specific Design: Kooks provides these kits for a variety of vehicles, such as Mustangs and Dodge Challengers, to ensure a proper fit and optimal performance
