Kooks Headers 2260H640 2in x 3in Stainless Long Tube Headers with H.O. Green Catted OEM Connection Kit

The Kooks Headers 2260H640 is a complete 2-inch x 3-inch stainless steel long tube header kit designed for the 2016–2020 Chevrolet Camaro SS and ZL1. This kit pairs performance-engineered long tube headers with High Output Green Catted OEM-style connection pipes for a bolt-in-style upgrade that connects directly to your factory exhaust (note: factory exhaust must be cut to install). No additional parts are required to complete the installation.

The included High Output Green Catted connection pipes measure 3 inches x 2-3/4 inches and are designed to mate with the OEM exhaust system. The H.O. Green Cats feature an advanced precious-metal coating that enables proper catalytic function even under the extreme heat demands of high-horsepower and forced induction applications, and are rated for forced induction builds up to 1,000 horsepower.

Key Features:

• 2 in. primary tubes with 3 in. collector diameter — optimized for maximum scavenging and flow
• Constructed from T304 aircraft-grade stainless steel for superior heat resistance and long-term durability
