JBA has been building and testing headers for the GEN3 HEMI since it was introduced in 2003. 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 1-7/8" 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. 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
