A header is a component of an exhaust system that is designed to improve the engine's performance. It replaces the original exhaust manifold that comes with the car, which is usually quite restrictive. Headers are designed to help the exhaust gases exit the engine more efficiently, which in turn increases the power and efficiency of the engine.
A manifold, also known as an exhaust manifold, is the part of the engine that collects the exhaust gases as they leave the engine's cylinders. It then directs those gases to the exhaust system. The original manifold that comes with the car is usually designed to save money on manufacturing costs, and therefore, it is not always the most efficient design.
Headers are known to be better than manifolds because they are designed to improve the performance of the engine. They are usually less restrictive than the original exhaust manifold that comes with the car, which means that the engine can breathe more easily. This results in increased power and efficiency. Headers are also known to produce a better exhaust note than manifolds, which can add to the overall driving experience.
However, headers can be more expensive than manifolds, and they may require modifications to the exhaust system in order to fit properly. They can also be more difficult to install than manifolds, which means that it may take longer to install them.
On the other hand, manifolds are usually cheaper than headers, and they are easier to install. However, they may not offer the same performance benefits as headers, and they are usually less efficient than headers. This means that they may not be the best choice for those who are looking to improve the performance of their car.
Headers and manifolds are both important parts of an exhaust system, and they each have their pros and cons. If you are looking to improve the performance of your car, headers are usually the better choice. However, if you are on a budget or if you are looking for an easier installation process, manifolds may be the right choice. Ultimately, the choice between headers and manifolds depends on your specific needs and preferences.
