Headers generally use piping with a wider diameter than factory tubing, which allows more air to pass through the exhaust system than factory. The easier an engine breathes the more power it produces. Q: What does a header do? Why buy a header? A: An exhaust header is a performance product that replaces your factory exhaust manifold and improves an engine's performance by allowing air to flow more freely. Either way, you're going to be getting more horsepower from a header. The 4-1 design maximizes top end power, whereas the 4-2-1 evenly distributes it throughout the power band. In many cases 4-1 headers are designed for racing applications where the vehicle is being driven at or near redline. Q: What are the different tubing options for headers and what is the difference between them? A: There are two major designs for headers: the 4-2-1 design and the 4-1 design. ![]() The answer is yes in almost every case, as the Chevrolet El Camino headers are still designed with flanges in most cases that will mount right up to the existing factory parts. We get asked a lot if you can buy Chevrolet El Camino headers but still leave the stock catalytic converter in place. Some of the popular brands of headers that you'll find are: DC Sports, Hedman, Hooker, Doug Thorley, Pacesetter, and Flowtech, among others. The headers are often connected to the catalytic converter, which is connected to the muffler and exhaust tip, so the headers are the "front" of the exhaust system. Right after the incoming air and fuel combust, the result exhaust is push through the headers and out the exhaust. Headers are considered part of the exhaust system of the vehicle. Headers are normally designed to be less restrictive than the factory exhaust manifolds that they replace, thereby generating more horsepower. Chevrolet El Camino Header is the term used to describe the aftermarket product that replaces the factory exhaust manifold.
