Your Vehicle Catalytic Converter. "Indomie"

About a vehicle's catalytic converter "indomie"
 
A catalytic converter is a large metal box, bolted to the underside of your car, that has two pipes coming out of it. One of them (the converter's "input") is connected to the engine and brings in hot, polluted fumes from the engine's cylinders (where the fuel burns and produces power). The second pipe (the converter's "output") is connected to the tailpipe (exhaust). As the gases from the engine fumes blow over the catalyst, chemical reactions take place on its surface, breaking apart the pollutant gases and converting them into other gases that are safe enough to blow harmlessly out into the air. 

WHY IS THE CATALYTIC CONVERTER EXPENSIVE 

The catalytic converter is constantly being targeted by thieves is because the catalyst is made up of a mix of precious metals. 

Platinum is the most active catalyst and is widely used in the manufacture of the catalytic converter including Palladium and Rhodium. Copper, Cerium, Manganese and Nickel are also used. 

These are very expensive precious metals and are highly sought after around the world. The average price for the content of a catalytic converter in the metal black market ranges from 2000 naira to 10,000 naira. Replacing them could cost between 20,000 naira to 150,000 naira depending on your car model.
