The catalytic converter is made with trace amounts of platinum, palladium and rhodium, which speed chemical reactions and help clean emissions at very high temperatures. Selling stolen converters to scrap yards or recyclers, a thief can net a couple of hundred dollars apiece.
The purpose of any catalytic converter is to reduce harmful emissions from the exhaust of a properly tuned combustion engine. It accomplishes this through a combination of heat and aprecious metal catalyst that causes the harmful emissions to either oxidize or reduce to safe elements in the exhaust flow.irst, the carbon deposits prevent the catalytic converter from reducing harmful emission in the exhaust flow. And second, the carbon deposits clog the pores in the ceramic catalyst and block exhaust flow, increasing backpressure and causing heat and exhaust to back up into the engine compartment.
