Description
The Kooks 22605301MD 3″ GREEN Catted Header-Back Muffler Delete Exhaust System is the most aggressive, free-flowing full exhaust upgrade Kooks offers for the 2016–2024 Camaro SS and ZL1. Designed as a complete header-back system, it replaces every part of the factory exhaust from the collectors to the exhaust tips, delivering massive increases in exhaust flow, horsepower, torque, and sound.
This system features 3-inch mandrel-bent 304 stainless steel tubing, a performance-engineered X-pipe, GREEN high-efficiency catalytic converters, and a muffler delete configuration, producing a raw, race-inspired exhaust tone. Expect maximum volume, crisp throttle response, and an extremely aggressive sound profile under acceleration.
Finishing the system are two 4-inch polished stainless steel slant-cut tips, offering a clean, premium appearance from the rear of the vehicle. Designed for drivers seeking maximum performance, maximum sound, and superior durability, the GREEN Catted Header-Back Muffler Delete system is ideal for high-power LT1 and LT4 builds—naturally aspirated, supercharged, or cammed.
