It's a big chunk of cast metal that bolts to the exhaust ports of an engine and joins up with the exhaust pipe. In a 4-cylinder engine, usually all 4 ports connect to just one exhaust pipe. In a six, usually the exhaust ports are combined 3+3 and then each bank of 3 either has its own exhaust pipe, or they are combined again somewhere underneath the car into just one pipe.
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 purpose of the exhaust manifold is to connect the exhaust ports on the cylinder head to the exhaust pipe.

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.

Where is the leak coming from. Most likely you will need to replace the exhaust manifold gasket which will require removing the exhaust manifold.
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.
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.
The intake manifold is where the air and fuel mix and enter the engine. The exhaust manifold is where unspent gas and air exit the engine. In other words the intake manifold is where the engine breathes in and the exhaust manifold is how the engine exhales out.
have you checked to see if there is any broken bolt on the manifold, or worped manifold, burnt manifold gasket
