What is an exhaust manifold?

An exhaust manifold is part of the exhaust system and sits right on top of the cylinder head. It takes exhaust gases collected from the individual cylinders to the turbocharger or to a collector pipe. As such, it’s one of the most stressed components in your car. The forces at work on the manifold are immense, especially given its exposure to extreme heat from the exhaust gases (which can reach over 1,000°C). Consequently, materials play a major role: many turbo manifolds are made from cast iron or stainless steel and often feature special alloys. Particularly in motorsport, where high performance is another factor that pushes up the temperature, the materials used have to be correspondingly tough. At the same time, every gram counts on the racetrack, so weight-saving stainless steel is becoming more and more popular.

How does the exhaust manifold work?

The exhaust manifold is designed to take away the exhaust gases from the individual cylinders. And that’s exactly why it’s curved. The hot exhaust gases from the cylinders flow through the turbo manifold and onwards to the turbocharger or a pipe, where they’re collected. At this point, they’re cleaned and taken to the exhaust system. Exhaust gases from the engine usually enter the manifold horizontally and are ducted downwards from there.

In tuning, the goal is to streamline the manifold as much as possible so that it discharges the exhaust gases quickly and efficiently, preventing them from flowing back into the cylinders. Manifold designs differ according to the ignition sequence because the exhaust gases flow into the manifold so fast that they create a vacuum that sucks them in and almost out of the engine. This applies particularly to sophisticated header designs.

Pipe length and diameter, pipe joints, and welds are key criteria in high-performance exhaust manifolds. These factors can have a big influence on the gas flow. For example, weld roots inside the pipes can cause turbulence. So the manifold interior has to be as smooth as possible to guarantee the optimum flow ratio.
