Exhaust System

The three-way catalytic converter (TWC) acts by oxidizing carbon monoxide (CO) and hydro-carbons (HC) to water and carbon dioxide (CO2 ). Nitrous oxides (NOx ) are reduced to nitrogen and water. Over 98% of these substances are converted in the three-way catalytic converter (TWC) during normal driving. Lead pollutants in the fuel damage the three-way catalytic converter (TWC) and can quickly render it unusable.
