The exhaust system is one of the most important components in any vehicle. This system carries away the poisonous gases created by the combustion process, reduces the level of engine noise, and reduces engine emissions. Designing such a system requires careful research because each vehicle is different. A flawed system design can restrict the flow of gases, reduce horsepower and fuel mileage, and cause engine damage.

Exhaust headers are among the popular bolt-on parts that can improve your engine's performance. The basic idea behind this component is that it eliminates the manifold's backpressure. Each cylinder has its own exhaust pipe, and each pipe merge together in a larger pipe known as the collector. The individual pipes are bent and cut to make sure all are uniform in length. Once each of the cylinder's exhaust gases arrives in the collector, there's no backpressure because all gases are spaced out equally.

If you're planning to use a car exhaust header for your vehicle, be sure to select the correct one for your personal needs. Drivers who usually roam around the city would be better off using a low-performance exhaust header, while those who are looking for speed will need to install a high-performance header. Other header types are small block headers that use 1 3/8-inch tubes, and big block headers that employ 1 3/4-inch tubes. Higher-quality headers range between 14- and 18-gauge. The header's primary pipe diameter and primary pipe length will indicate the engine's overall power band and peak power.

Exhaust headers can be constructed from mild steel or stainless steel. One advantage that stainless steel headers have is that they won't rust, but you have to spend more for one. On the other hand, mild steel headers have a ceramic or paint coat that can withstand high temperatures. If you can spring for it, go for the stainless steel variant so that you won't have to deal with rust in the future. Corrosion can be a major pain because it not only affects the headers but also other parts such as pipes, catalytic converters, mufflers, and tail pipes. Deterioration of these parts usually occurs from the inside out, making it difficult to check on their condition with just a simple visual inspection.

If you install headers, make sure that they're installed properly. The exhaust system could leak when the headers are improperly installed. Have a professional mechanic install it for you.
