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.

A vehicle's exhaust manifoldplays 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. N...
Cast iron exhaust manifolds last a long time and they are cheap to make. That is why so many cars and trucks come with them from the factory. In modern cars, exhaust manifolds are designed to fit into small spaces and live long lives. Maximizing horsepower is rarely a factor. That is why cast iron exhaust manifolds are often replaced with more free...
Since tubular steel exhaust manifolds typically have better flow, they are most often found on performance-oriented applications, like sports cars, but there are a few automotive manufacturers out there that prefer using tubular manifolds on non-sport models as well, like Jeep. This style exhaust manifold can be made from mild steel or stainless st...
Many people ask what the difference is between an exhaust manifold and a header. An exhaust manifold is an OEM-style part. Aftermarket exhaust manifolds look and fit just like the exhaust manifold that came on the car when it was new, with similar flow characteristics. Like we mentioned in the "cast iron" section above, exhaust manifolds are often ...
A cracked or broken exhaust manifold is most often caused by one of two things: The first is heat cycles and/or age. Over time, the manifolds just can't take the heat anymore (literally and figuratively), and cracks begin to form in them. The cracks then turn into small holes, and it doesn't get any better from there. The second common reason for e...
Replacing an exhaust manifold will be a different procedure for each vehicle, so grabbing a service manual is a great start. That being said, there are a few noteworthy tips for replacing any exhaust manifold. 1. Spray the bolts with some type of rust penetrating fluid in advance so that removing them is drama free. 2. If the oxygen (O2) sensoris i...
As you can imagine, we have an absolutely massive selection of exhaust manifolds available. We carry the cast iron and tubular steel type, depending on the application. They are designed to look and fit just like your OEM exhaust manifolds do. Many of them even have reinforced designs that help them survive far longer than the original manifold did...
The exhaust manifold collects the exhaust gases from the individual ports in the engine’s cylinder head, then routes those gases to the rest of the exhaust system. Catalytic Converter. The catalytic converter is an emissions control device that converts harmful exhaust gases into water, carbon dioxide, and nitrogen.
Nov 23, 2017 · The engine exhaust manifold in your car is linked directly to the cylinders where gas and oxygen mix together before being ignited by a spark plug. Once the fuel has been burned, the cylinder’s exhaust valve opens up to allow the waste gases to escape, sending them out into the manifold. While the pressure inside the cylinder is strong enough ...
Oct 14, 2019 · A car’s exhaust manifold is used to take the exhaust gases from the engine to the exhaust pipe beneath the car body. Manifolds are usually made from tubular steel, stainless steel or iron. Stainless steel is the most expensive because it doesn’t rust and lasts for a very long time, but tubular steel is also highly rated for its good gas flow.

The exhaust manifold is bolted directly to the engine block and is the first section of a vehicle’s exhaust system. It collects exhaust gases from all the cylinders and directs 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 allow exhaust ...
