upon failure, a catalytic converter can be recycled into scrap. the precious metals inside the converter, including platinum, palladium, and rhodium, are extracted.









































section::::placement of catalytic converters.









































catalytic converters require a temperature of 800 degrees fahrenheit (426 °c) to efficiently convert harmful exhaust gases into inert gases, such as carbon dioxide and water vapor. therefore, the first catalytic converters were placed close to the engine, to ensure fast heating. however, such placement can cause several problems. one of these is vapor lock.

free-flowing exhaust systems may maximize peak horsepower by reducing or eliminating back pressure; this is typically accomplished by making the path as straight as possible, using a consistent diameter throughout the system and eliminating obstacles such as catalytic converters and pre-catalytic converters or by replacing the muffler with a less restrictive (and usually louder) one. despite the potential for increased performance by eliminating catalytic converters and other emissions control hardware, doing so will often render the vehicle illegal for street use in many jurisdictions. other aftermarket modifications that bypass the catalytic converters and/or mufflers, such as electric or cable activated exhaust cutouts—which open and reroute the exhaust flow to bypass restrictions in the system—can similarly increase performance, though would likely be illegal in areas where tampering with emissions devices is prohibited, particularly when placed in front of the catalytic converters.
