A catalytic converter is one of the key components of a modern exhaust system. It essentially works as a filter that converts the most harmful components of exhaust gas into less environmentally damaging compounds. The most poisonous exhaust gases are carbon monoxide, nitrous oxide, sulfur dioxide, and a mix of various hydrocarbons.

The Toyota T100 catalytic converter, like all other cats, uses a mesh of precious metals of the platinum family of elements to convert the pollutants. Because they contain precious metals, they tend to be the most expensive portion of an exhaust system.

The best catalytic converters have the greatest amounts of these metals, allowing the exhaust to move through quickly and efficiently. A less expensive catalytic converter can be considered a high flow performance cat if the input and output ports are larger than stock. Larger ports are less restrictive, allowing a higher volume of gas to move through at a lower pressure. Lower back pressures mean that the engine will not have to work as hard to move the gas, taking some of the load off of the piston at the exhaust stroke. If you smell rotten egg smell from your exhaust, your Toyota T100’s catalytic converter is likely failing. A failed catalytic converter will not only allow more environmentally damaging compounds into the air, but it can actually hurt your engine’s performance, robbing you of valuable horsepower.
