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.
