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.
The intake manifold distributes the air fuel mixture from the carburetor to the cylinders. The exhaust manifold collects the exhaust gases from the cylinders and directs them out the exhaust pipe.
Carry away exhaust gases from the engine. Intake carries a/f mix to cylinders.
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.
exhaust manifold is where exhaust pipe hooks to engine!

You will need to remove the exhaust manifold retaining bolts in your 1993 Chevy Astro. Remove the exhaust manifold. Remove the exhaust manifold gasket and clean the surface. Reverse the process to install the new exhaust manifold gasket.

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.
Intake manifold delivers the fuel air mixture to the cylinder heads, exhaust manifold collects the gases after combustion, and channels them into the exhaust pipe.
