JBA 1-3/4" Shorty Headers T409 Stainless Steel for 09-22 Challenger, Charger R/T & 300C 5.7L

part number: 1964S-1

JBA has been building and testing headers for the new HEMI since it was introduced in 2003. Will work on the older square port 5.7L heads - call for further info. With this experience their 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 factory 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 with a port matched flange, back pressure is reduced and flow goes way up. The giant 3" collector was engineered using JBA's patented Firecone - a unique directional device similiar 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 engine. Benefits: Increase hp & torque throughout RPM range Improved throttle response Reduced back pressure Reduced under hood temperature Increased passing power Increased low-end torque Makes engine more sensitive to other modifications (intake, chip, supercharger, etc.) Improved engine compartment appearance Disclaimer: For off road or racing use only
