Choosing the right exhaust headers for your vehicle is important because they can improve engine performance, increase horsepower, and enhance the sound of your exhaust. When selecting exhaust headers, there are several factors to consider, including the type of engine, the size of the engine, and the desired sound.
There are two main types of exhaust headers: equal-length headers and unequal-length headers. Equal-length headers are designed to provide equal exhaust flow to each cylinder, which can improve engine performance and increase horsepower. Unequal-length headers are designed to create a scavenging effect, which can help to improve exhaust scavenging and increase horsepower at higher RPMs.
