Headers, also known as exhaust headers or exhaust manifolds, are an important component of the engine's exhaust system. They are designed to collect & channel the exhaust gases from each individual cylinder of the engine into a single exhaust pipe. Unlike the factory exhaust manifolds, which are typically restrictive & have a common collector for all cylinders, headers are designed with individual tubes for each cylinder, allowing for improved exhaust gas flow & scavenging. By optimizing the exhaust flow, headers can enhance engine performance by reducing backpressure & increasing horsepower & torque output. They also contribute to a more aggressive & distinctive exhaust sound. Headers are commonly made from stainless steel, mild steel, or other high-quality materials to withstand the high temperatures & corrosive gases present in the exhaust system. Properly designed & installed headers can provide significant performance gains, especially when combined with other exhaust system upgrades such as high-flow catalytic converters & cat-back exhaust systems. It's important to consider factors such as compatibility with the engine & vehicle, emission regulations, & professional installation when selecting & installing headers to ensure optimal performance & reliability.
