Exhaust Manifolds vs. Headers
Many people ask what the difference is between an exhaust manifold and a header. An exhaust manifold is an OEM-style part.Aftermarket exhaust manifoldslook and fit just like the exhaust manifold that came on the car when it was new, with similar flow characteristics. Like we mentioned in the "cast iron" section above, exhaust manifolds are often designed with longevity and fitment in mind, not horsepower. Headers on the other hand are designed purely for maximum horsepower and torque. They are built with steel tubing, they are often mandrel bent, and most have equal length piping so that each cylinder has similar flow. Headers can be tuned to gain more or less performance in certain areas of the engine's power band. For maximum benefit, a full performance exhaust would be necessary when using headers, because great flowing headers are worthless if the pipes after them are overly restrictive.
