Exhaust manifolds are in general simple cast iron devices which collect motor smoke from all the cylinders & distributes it to the tail pipe. As an engine starts its exhaust stroke, the piston moves up the cylinder bore, decreasing the total volume of the piston chamber. With the exhaust valve open, presurized exhaust gases escapes into the exhaust manifold, causing an exhaust pulse.

For lots of engines, high performance after-market exhaust headers are offered. These consist of particular exhaust headpipes for each cylinder, which then regularly come together into one tube called a collector. Some recent exhaust headers are available lined with ceramics. Ceramic coating helps to prohibit rust and to reduce the quantity of heat radiated into the engine bay. The heat reduction will help thwart intake manifold heat soak, which will decrease the temperature of the air going into the motor.
