Along with a high performance cold air intake and high-flow air filter, headers reduce exhaust backpressure for air to flow more easily out of the engine. Headers work by providing each cylinder with its own mini exhaust pipe and piping exhaust pulses away from the cylinder head into a downstream exhaust collector, improving air intake and exhaust.
Headers come in different sizes and shapes with hundreds of applications to suit your particular car's needs. Top manufacturers produce their own headers in various configurations, specially tuning each to fit the type of engine it is intended for. So whether you have an imported or domestic vehicle of whatever brand, there's an exhaust header just for you! If you're obsessive-compulsive with your car's looks even with the under hood, then worry not as headers are also available in different finishes that complement that hidden part of your car.
