Headers are exhaust manifolds. They connect to your "heads" to allow the exhaust from the combustion chamber to exit though the exhaust port into the exhaust manifolds or "headers" and into the exhaust system.
Cats are catalytic converters. Our trucks have one round style catalytic converter attached to the end of each exhaust manifold (header).
So the connection points are: head, exhaust manifold (header), catalytic converter, exhaust pipe, and then muffler(s) back to tail pipe.

From Wikipedia:
A catalytic converter (colloquially, "cat" or "catcon") is a device used to reduce the toxicity of emissions from an internal combustion engine. First widely introduced on series-production automobiles in the U.S. market for the 1975 model year to comply with tightening EPA regulations on auto exhaust, catalytic converters are still most commonly used in motor vehicle exhaust systems. Catalytic converters are also used on generator sets, forklifts, mining equipment, trucks, buses, trains, and other engine-equipped machines. A catalytic converter provides an environment for a chemical reaction wherein toxic combustion by-products are converted to less-toxic substances.
