Air injection pipes are constructed utilizing a combination of materials such as plastic tubes, metal tubes, and rubber hoses. They are basically an air manifold assembly that routes pressurize air from the air pump to the exhaust manifold. The oxygen mixes with the exhaust gases to burn them instead of them just exiting through the exhaust pipe. This process also improves the efficiency of the catalytic converter. The burning gases assist the catalytic converter in the warming process when a cold engine is started. The end result is less exhaust gases being emitted through the exhaust which reduces pollution levels created by automobiles.
