The Kooks Long Tube Header Kit features 2-inch stainless primary pipes with 3-inch outlets, engineered specifically for 2015+ Dodge Hellcat models. Designed to optimize exhaust scavenging and reduce backpressure, these headers improve engine breathing and thermal efficiency while maintaining compatibility with factory exhaust configurations via OEM-style connections. Built for durability and performance, the system includes Kooks’ GREEN catalytic converters, which are designed for enhanced flow while meeting stringent emissions compliance.
Each header is made from mandrel-bent stainless steel and TIG-welded for strength and precision. The stepped design and smooth transitions help reduce turbulence, improving exhaust velocity for better power delivery across the RPM range. This setup is ideal for high-horsepower builds and performance-tuned street vehicles that demand reliability and flow efficiency. The direct-fit construction minimizes modification during installation while retaining factory mounting points.
