1. manifold; 2. gasket; 3. nut; 4. heat shield; 5. heat shield bolt. Ceramic-coated exhaust manifold on the side of a performance car. In automotive engineering, an exhaust manifold collects the exhaust gases from multiple cylinders into one pipe. The word manifold comes from the Old English word manigfeald (from the Anglo-Saxon manig [many ...
Sep 27, 2023 · An exhaust manifold collects exhaust gases from multiple cylinders into one pipe, serving as the first component in the exhaust system of a vehicle. This essential automotive part directs the exhaust fumes to the catalytic converter, and in turbocharged engines, it is located downstream of the exhaust manifold.
Bolted directly to the engine block, the exhaust manifold is the first section of a vehicle’s exhaust system. It funnels exhaust gases from all the cylinders and routes them to the car’s catalytic converter. V-type engines have a separate manifold for each cylinder bank. A leak in the exhaust manifold or its gasket can.
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.
The system consists of an exhaust manifold, catalytic converter, O2 sensors, exhaust pipes, a muffler, a resonator, a tailpipe, and other miscellaneous components (e.g. gaskets, heat shields, and hangers). The leaking exhaust system can expose you to high amounts of carbon monoxide. An obstructed exhaust system can also create back pressure ...
Exhaust manifolds are made from different materials like cast iron, stainless steel, and titanium. Each of these materials has its own advantages and disadvantages. 1. Cast Iron Exhaust Manifolds. Exhaust manifolds made from cast iron are used on several vehicles and are relatively cheap. This material is durable and can have a long life span.

A vehicle's exhaust manifold plays the leading role in a car or truck's exhaust system. It connects to each exhaust port on the engine's cylinder head, and it funnels the hot exhaust to the exhaust pipe. With the help of the exhaust manifold gaskets, it also prevents the toxic exhaust fumes from sneaking into the vehicle and harming the occupants.
