For further information, see "Computer controlled catalytic converter for Fiat 500 and Fiat 126".

CAUTION: Most Fiat 500 models are now equipped with the 600ccm / 650ccm engines that were originally fitted to the Fiat 126 model. Please confirm which engine you have by checking the engine number before placing your order.

Important information:
Exhaust systems are welded parts. Due to warpage during manufacturing, friction may occur in the exhaust pipes after installation - the consequences are cracks or breaks in exhaust pipes and welds. To avoid this, all exhaust systems for Fiat 500 and Fiat 126 should be annealed to get tension-free after installation! There is no warranty on cracks or breaks on exhaust pipes or weld seams!

The Catalytic Converter

The purpose of a catalytic converter is to initiate or accelerate a chemical process. A catalytic converter, or more precisely, the chemical substances that initiate catalysis, are not consumed in this process and remain unchanged at the end of the catalysis. The catalytic converter, colloquially referred to as "cat," is used to reduce pollutants in the exhaust gases of internal combustion engines. In automotive technology, the term catalytic converter generally refers to the entire system of catalytic exhaust gas purification, but, upon closer inspection, multiple components such as lambda sensors, EGR valves, and/or particulate filters work together seamlessly.

During the combustion of gasoline in a gasoline engine, harmful exhaust gases such as carbon monoxide, hydrocarbons, and nitrogen oxides are produced. When burning diesel fuel in a diesel engine, additional pollutants include soot particles and sulfur dioxide. In a regulated (three-way) catalytic converter, harmful carbon monoxide is converted to carbon dioxide, hydrocarbons to carbon dioxide and water vapor, and nitrogen oxides to nitrogen.

A catalytic converter consists of a metal housing containing the substrate that triggers the catalysis. This substrate is traversed by many fine channels, increasing the surface area of the substrate. The larger the surface area, the more exhaust gas can be processed. The hot exhaust gases exit the engine, pass through the surface inside the catalytic converter, and are expelled cleansed through the exhaust.

The vehicle's catalytic converter typically employs three precious metals: rhodium, platinum, and palladium. Platinum is responsible for chemical oxidation processes, rhodium for reduction processes, while palladium ensures higher resistance of the sensitive catalytic surfaces to sulfur. Other crucial components for the effective operation of a catalytic converter include high temperatures (500 degrees) and the correct composition of the exhaust mixture. The high temperature is achieved by placing the catalytic converter immediately after the hot combustion chambers, and the exhaust mixture is controlled, among other things, using a lambda sensor, exhaust gas recirculation, and engine control.
