Exhaust Header VS Manifold, which is the better choice? 

The structural differences between exhaust headers and manifolds lie in both material and design. Headers are made from lighter, thinner steel, while manifolds are typically cast from heavy, thick iron. SBC S10 headers are also longer in shape, allowing for improved exhaust flow. Unlike manifolds, which can create back pressure and reduce engine performance, headers give each cylinder its own tube, helping exhaust gases exit more efficiently and eliminating back pressure. That’s why S10 V8 headers are a superior choice for performance builds and engine swaps.
