That's where exhaust headers is significant as the first revenue of an exhaust system. Exhaust performance headers manipulate the air flow with the performance-robbing exhaust manifold that came with your car. Headers provide each cylinder with its own mini exhaust pipe, which means exhaust headers prevent interference among cylinders; thus, the back pressure that occurs in common exhaust manifolds. When cylinders don't have to fight with each other to expel their exhaust, they can put more power through the wheels, pushing the vehicle. Combining with a high performance cold air intake, and a cat-back exhaust system, a header system removes all restrictions of your engine, then, it is able to perform at its full potential. 2014-2018 Chevy/GMC Silverado & Sierra 1500 5.3L & 6.2L V8 2WD & 4WD Exclude Mid-Year Change 2018.5+ New Body Style Tube Diameter: 1-7/8" Collector Diameter: 3" Y-Pipe Included With This Kit Black Coated To Ensure Durability TIG Weld & Mandrel-Bent For Maximum Performance Improve Sound, Horsepower & Torque Gasket, Exhaust Clamps & Head Bolts Included Quality & Affordable Products No Instruction, Professional Installation Recommended Terms & Conditions By making this purchase, the customer has fully agreed to all Terms & Conditions as stated below Customers are ultimately responsible for ensuring the items purchased are correct for their vehicles No returns or exchange on any item that has been used.
