JBA 1964S-1JS Silver Ceramic Coated Headers for 2009-2020 Challenger Charger 300 Magnum 5.7 Hemi

JBA 1964S-1JS Silver Ceramic Coated Headers for 2009-2020 Dodge Challenger Charger Magnum Chrysler 300C 5.7 Hemi

JBA has been building and testing headers for the 5.7L HEMI since it was introduced in 2003. With this experience our engineers were familiar with the design and flow characteristic of the heads and knew what the engine would respond best to. The engineering team at JBA addressed the critical short comings of the 5.7L HEMI exhaust manifolds with a fresh design that started with high flowing 1-3/4" mandrel bent stainless steel tubing. By giving each cylinder a smooth unrestricted path, back pressure is reduced and flow goes way up. The giant 3" collector was engineered using JBA's patented Firecone® - a unique directional device similar to what you find on a long tube race header - which improves flow by providing efficient scavenging of exhaust gasses. Other standard features like thick 3/8" CNC laser-cut flanges, O.E. style JBA sealing dome connection to the exhaust and high quality hardware make them a highly effective upgrade for the HEMI.
