All over your truck, you can find many stock parts designed to be more economical but end up compromising your truck's performance. Stock headers are notorious for this, and that's why Banks Headers are designed to recover that compromised power. Most stock headers feature one single intake manifold that attaches to each of your cylinders. This presents a problem in four-stroke engines, which only produce real power in every four strokes - the power stroke. Each other stroke is necessary for intake and exhaust purposes, but each one uses power. Meanwhile, air backs up in that single manifold during each of these strokes, and it hinders the performance of your engine. Banks Headers remedy this by attaching individually to each cylinder. The piping that attaches the headers is cut so that air entering the headers is distributed evenly and reaches each combustion chamber at the same time, curtailing back pressure. This way, the engine is not compromised as it originally was, and it frees up the engine to put out the power it was designed to in each power stroke. A set of Banks Headers will then make your engine work more efficiently, and your truck will benefit greatly from the increased horsepower and torque.
