CATALYTIC CONVERTER
An exhaust pipe does more than simply divert the waste gases from combustion away from the engine. It must also treat them to ensure no harmful toxins flow out and into the air that we breathe. An important device for vehicle emission control, the catalytic converter (cat-con) uses a catalyst to eliminate the release of toxic gases into the air from the vehicle’s exhaust stream. In bikes, it is a honeycomb metal structure that incorporates precious metals like palladium, rhodium, or platinum into its surface. These metals convert poisonous carbon monoxide (CO) and unburned hydrocarbons (HC) found in exhaust gases into non-toxic carbon dioxide (CO2) and water vapour. However tempting it may seem, a free-flow exhaust system is not road-legal with track-only use allowing for specially-tuned unrestricted passage of the exhaust stream
