The Kooks 2261H630 2" Stainless Steel Long Tube Headers with GREEN Catted OEM Connection Kit deliver maximum exhaust flow, increased horsepower, and improved throttle response for the 2016–2024 Camaro SS and ZL1. Designed specifically for the LT1 and LT4 engines, these long tube headers use 2-inch primary tubes and 3-inch collectors to dramatically improve exhaust scavenging and high-RPM performance.
Included with the headers are Kooks GREEN high-efficiency catalytic converter OEM connection pipes, which reduce emissions, minimize odor, and maintain strong exhaust flow. These 3" to 2.75" connection pipes allow seamless installation to the factory Camaro exhaust system without additional adapters. Everything needed for installation—gaskets, clamps, O₂ ports, and hardware—is included.
If you're building a high-performance Camaro SS or ZL1 with tuning, cam upgrades, or forced induction, the 2" primary headers offer superior top-end power potential while maintaining exceptional durability with premium 304 stainless steel construction.
