Like exhaust manifolds, headers are designed to route exhaust gases from the engine to the exhaust system. The primary difference is that headers create less exhaust backpressure than exhaust manifolds, thereby allowing the engine to breathe more easily. Headers are usually made from thin-walled stainless steel tubing.Why are headers are a better choice than an exhaust manifold? As stated above, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure.In general, a quality set of headers should provide an increase of approximately 10-20 horsepower, and if you’re restrained with your right foot, you may even see an increase in fuel mileage.
