The answer is no they are not the same thing. BUT they do perform the same FUNCTION. The function is that the reduce several exhausts ports into one exhaust pipe. I will use a V8 motor for an example. A V8 motor has 8 exhaust ports that are split between two cylinder heads. 4 exhaust ports each. One bank of four on each side of the motor. An exhaust manifold and an exhaust header also have four ports on the flange where they bolt up to the exhaust ports on the cylinder head. Here is how they differ. a manifold is exactly that-- a manifold meaning it is one hollow chamber that is cast with 4 flanged holes formed into the side of it and one large hole that is cast and flanged at one end on the bottom side of it. And the large hole is where the one pipe connects. So you would have on a V8 motor eight exhaust ports that dump into two exhast manifolds and travel through two pipes 1 on each side if it is a dual exhaust system that is . If it is a single exhaust system then the two pipes coming off of the manifolds are reduced further and joined together somewhere in the center of the car and both flow into one singular pipe. A header's function is to direct the exhaust from each port through an individual pipe and each pipe is joined at a collector box that is joined to one large diameter pipe that is short in length and is straight. These individual pipes are the same diameter as the ports that are on the heads and any changes in the flow are long sweeping curves that are smoooooth. So in effect what happens is you get an extended ehaust port length and no drop in pressure. in fact because there is no pressure drop, and you just made that exhaust port 4 feet longer you get even more pressure and when it finally does release in the collector box that extra pressure becomes propulsion. which reults in increased horsepower and performance. In fact I am confident that every header manufacturer will easily guarrantee an increase of 15 or 20 horsepower to any motor simply by just taking off the manifolds and putting headers in their place alone. With no other modifications whatsoever. That is a dramatic increase in power and its simple to do. I hope that answered your question. May the God of your choosing Bless you.
The exhaust manifold is the header that starts at the piping on the driver's side of the engine and runs back out to the exhaust.
Header or headers are a high performance version of an exhaust manifold
A formatted header is part of the exhaust manifold that is used to direct exhaust gasses into the open atmosphere
i header is much better than a manifold better it will give you increased air flow horse power and gas mileage

The part your talking about conects to your manifold or header then goes to you exhaust i wonderd the same thing for a while.
under the intake manifold-its most likely a header assembly on 4.0 engines. Steve
The shift sensor may be found either on the exhaust manifold, where the exhaust pipe enters the engine block, or it is attached directly in the header pipe beneath the exhaust manifold.
An engine has one header(exhaust manifold) for each cylinder head it has.
The exhaust valve, the exhaust manifold, the header pipe, the catalytic converter, the muffler and the tail pipe, not to mention the clamps and hangers.
Since they are really the same thing, there is no answer. An exhaust manifold is a header and vice/versa.The common cast iron 'exhaust manifolds' are quiet, last forever, and cheap to produce. The headers you refer to are more expensive, short-lived and can be very pricey. But the first guy who bolted a pipe on the exhaust post of his single cylinder motor to keep from getting burned by the exhaust created the first header. He also created the first exhaust manifold. Take your pick.
It is not worth the effort since it will probably just crack again; cast iron does not weld well. Use this as a good excuse to put on a header. I got a nice stainless steel header for my 1991 4.0L for $185 including shipping. The exhaust manifolds are also known to crack. If you do not want a header, another option would be to watch for someone that did put on a header but is trying to get rid of the stock exhaust manifold they took off.
On every vehicle there are two manifolds. An intake manifold and a exhaust manifold. The intake supplies fuel and air to the cylinders. The exhaust collects exhaust from those same cylinders.
It would be a waste of time and money. You would have to make a special adapter to hook the exhaust to the manifold. On a turbo header, the exhaust hooks to the turbo and the turbo to the manifold.
An exhaust manifold or header collects the exhaust gases from multiple cylinders into one pipe. Usually constructed of cast iron, it conducts the exhaust gases from the combustion chambers to the exhaust pipe. It has smooth curves in it for improving the flow of exhaust. The exhaust manifold is bolted to the cylinder head, and has entrances for the air that is injected into it. It is usually located below the intake manifold. A header is a different type of manifold; it is made of separate equal-length tubes. There is also an intake manifold which directs fresh air, after it passes through the air filter and carburetor or throttle body, to the various combustion chambers (piston cylinders). And it should also be noted that, on some fuel-injected engines, what is often referred to as the fuel-rail, is also a manifold. It's purpose, of course, being the distribution of fuel to each injector.
No, Turboes require a special exhaust header/manifold and due to oil draining/lumbing regular header won't work/not worth the trouble.
Screwed into the exhaust manifold.Screwed into the exhaust manifold.
The exhaust manifold needs to have a gasket in place to help seal the juncture between the manifold and the engine. After the gasket and gasket sealer are in place, tighten the bolts for the exhaust manifold. The exhaust pipe can then be replaced on the new exhaust manifold.
The oil dipstick on the 1.6 goes into the center of the exhaust manifold (header). The 2.0 is on the passenger side of the header. Also if you have an se-r, it's a 2.0.
The purpose of the exhaust manifold is to connect the exhaust ports on the cylinder head to the exhaust pipe.
exhaust manifold is where exhaust pipe hooks to engine!
