The structural differences between exhaust headers and manifolds lie in material and size. Exhaust headers are made from lighter, thinner steel, while exhaust manifolds are crafted from thick iron. Additionally, headers are longer and more efficient, reducing the back pressure that manifolds create, which can hinder performance. By assigning each engine cylinder its own tube, headers allow exhaust gases to exit smoothly, improving flow and boosting performance.
