In an ideal world, your BF Falcon's engine will produce carbon dioxide as steam during the combustion process, but unfortunately, we don't live in an ideal world, and the hot temperatures that occur as a result of the combustion process also produce gasses such as nitrous oxide and carbon monoxide. These two byproducts are very harmful to the environment and humans, which is why every vehicle incorporates a catalytic converter in their exhaust system.
If you're looking for a brand new BF Falcon catalytic converter to replace your faulty one, or are just looking to upgrade into a high-flow, performance BF Falcon catalytic converter, then there are a couple of important factors you should consider when shopping, in order to get the right one. The single most important factor to pay attention to when buying a catalytic converter is the EPA compliance, which basically ensures the converter complies to environmental protection laws in Australia.
Then, you have to consider the type of catalytic converter. There are three basic types: diesel, two-way and three-way converters.
Diesel converters are used in diesel engines, and their purpose is to oxidise the unburn hydrocarbons and carbon monoxide and reduce them into carbon dioxide and water. These converters are very efficient and eliminate the black soot and diesel odour. However, these converters can't reduce nitrogen oxide gases into oxygen and nitrogen gas.

These converters are very efficient and eliminate the black soot and diesel odour. However, these converters can't reduce nitrogen oxide gases into oxygen and nitrogen gas.
Two-way converters are practically the same as diesel converters, as they perform the same two basic tasks - oxidising carbon monoxide and unburnt hydrocarbons into carbon dioxide and water. These converters were used in early petrol engines, but due to the fact that they can't deal with nitrogen oxide, they've slowly phased out of the market and are replaced with the more efficient three-way converters.
Three-way converters are the most efficient converters available nowadays, as they have the extra function of reducing nitrogen oxide into oxide and nitrogen. These converters are essential in states and countries where emission standards are strict, and if you're shopping for a brand new converter, you should definitely consider getting a three-way model.
And lastly, you have to consider between a direct and universal fit catalytic converters. Direct fit converters are made for a specific model, make and year of vehicle in order to ensure an easy, proper fit. Most of the time, you'll need to bolt it into your exhaust system and that's it. On the other hand, universal fit converters, can be made for a wide range of vehicles, and you'll likely have to perform some welding and cutting to install it into your system.
