But the Shorty headers are ideal for turbochargers. If you decide to install a header, consider going for the long tube one if you want maximum performance boosts. But a header is the way to go if you want your car to perform better no wonder performance enthusiasts prefer this aftermarket upgrade. Ultimately, your choice will trickle down to how you want your vehicle to perform. You can switch to a header or continue using the OEM manifold. The thin walls of the header also allow for better temperature expulsion, which enables you to enjoy a more comfortable ride. For that, it is used in high-performance cars as it allows the vehicles to breathe more easily and ultimately boosts horsepower. Also, each engine’s cylinder is assigned its own tube, which can further create back pressure problems.Ī header does away with this issue and allows exhaust gases to be expelled more efficiently. As mentioned, an exhaust manifold creates back pressure, and that lowers horsepower or performance. PerformanceĪ pipe header is generally a better option than an exhaust manifold. On the other hand, a pipe header has smoother walls that are roomy enough to allow for a faster flowing of exhaust gasses. The walls are also rough, which contributes to the slow flowing of the exhaust gasses and ultimately causes back pressure. However, this material is typically prone to cracking.Īlso, its thick walls leave small space for gasses to pass through. The cast iron enables the manifold to cope with the high heat and pressure from exhaust fumes. On the other hand, a pipe header is made of lighter and thinner steel and is longer than the manifold. A manifold is typically shorter and made of thick cast iron. The structural difference between a pipe header and a manifold is the size and material. Let’s get you into the details of what makes them different, although they are designed to serve the same purpose. So far, you know what a header and manifold are. But those with V-type cylinder arrangements (V6, V8) have two separate manifolds – one mounted onto each cylinder head. The only purpose of the manifold is to transport the exhaust gases from the combustion engine to the rest of the exhaust system, where they are expelled.Įngines with cylinders arranged in line typically have a single exhaust manifold. So, an exhaust manifold is needed to take the exhaust fumes off all eight cylinders into a single pipe. The word exhaust manifold implies that the component receives gases from multiple cylinders and then folds them into a single output, a tube leading to the exhaust.įor instance, an 8-cylinder engine comes with eight outlets, one outlet for every cylinder. Conversely, a pipe header consists of stainless steel or thick cast iron and is found on most standard production vehicles. It collects exhaust gases from the car’s engine and delivers them to the exhaust system. What is a Manifold?Ī manifold or exhaust manifold is a simple component that typically serves the same function as the header. That makes them ideal for vehicles that rely on low-RPM power, such as daily commuters. Last but not least, the Shorty headers work best in the idle to mid-RPM range. They have short tubes and are mostly found in hot rod cars. Lakester, as the name suggests, is designed for dry lake racing. As a result, they produce the highest horsepower and more low-end torque than similar 4-1 headers. The Tri-Y has a “Y” shape that enables the exhaust gases flowing from one tube to flow through it and scavenge air from the other tube. In addition, these headers are designed to handle any power modifications in the future. Long tube headers connect the engine to the mid-pipe, allowing major performance enhancements and aggressive sound. There are mainly four types of headers long-tube headers, Tri-Y headers, lakester headers, and shorty headers. That enables the engine to breathe easily. A header is added to boost the engine’s power by reducing exhaust backpressure as an aftermarket upgrade used on high-performance vehicles. The individual runners may have the same length or vary depending on the engine type. It is typically made of thin steel tubing with long runners for each port before merging. Let’s get started! What is a Pipe Header?Ī pipe header is an essential component that helps to route exhaust gases from the internal combustion engine to the exhaust system. Here we’ll look at pipe header vs manifold and give you all the info you need. In other words, a pipe header is an aftermarket upgrade meant to enhance performance, while the manifold often comes standard on most vehicles. But these are two different components, although they have the same function.Ī pipe header is usually used for high-performance applications, while a manifold is used on regular production vehicles. Many people often use the terms header and manifold interchangeably.
