Headers on Andy's Auto Sport TV!
Check out this episode of Andy's Auto Sport TV where we explain all the basics about headers. In the video, we explain why headers open up horsepower gains and explain the difference between different types of headers, such as stainless steel headers, ceramic headers, painted headers, and chrome headers. Featured brands of headers in the video include DC Sports headers, Gibson headers, and Doug Thorley headers. We also show how to install headers and then show the resulting horsepower gains with our dyno run results!

» DID YOU KNOW?
K5 Jimmy Header is the term used to describe the aftermarket product that replaces the factory exhaust manifold. Headers are normally designed to be less restrictive than the factory exhaust manifolds that they replace, thereby generating more horsepower.
Headers are considered part of the exhaust system of the vehicle. Right after the incoming air and fuel combust, the result exhaust is push through the headers and out the exhaust. 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.
Some of the popular brands of headers that you'll find are: DC Sports, Hedman, Hooker, Doug Thorley, Pacesetter, and Flowtech, among others.
We get asked a lot if you can buy K5 Jimmy headers but still leave the stock catalytic converter in place. The answer is yes in almost every case, as the K5 Jimmy headers are still designed with flanges in most cases that will mount right up to the existing factory parts.
