The Kooks assembly of 1-7/8-inch stainless steel headers with catted connections is designed to enhance exhaust flow on 2016–2023 Camaro SS and ZL1 models.
This complete header and connection system is constructed from mandrel-bent 304 stainless steel, delivering durable, high-performance flow characteristics. The 1-7/8-inch primaries merge into 3-inch collectors, feeding into Kooks’ high-performance GREEN catalytic converters that maintain emissions compliance while reducing restriction. Engineered for direct connection to the factory exhaust system, this setup preserves OEM fitment without requiring major modifications. The combination of large-diameter tubing and smooth transitions helps improve engine breathing under load, making it suitable for both naturally aspirated and supercharged LT engines.
