Back Direct-Fit Catalytic Converters are designed for easy bolt-on installation for the Professional Installer. No more welding, cutting and tube bending equipment is not required. Each is designed to exact original equipment specifications. The Direct-Fits are available for the most popular vehicle makes and models.
Universal Catalytic Converters are the basic building blocks for a comprehensive line of direct-fit applications. The main benefit of the universal catalytic converter is the low price , because you do not need to change the pipes or the all unit, in vehicles with two or more catalytic converters we will replace just the wrong converter and you will save money. The catalytic converter is a device located in the exhaust system of all modern motor vehicles. It is an important device in the exhaust gas de-pollution process, which reduces harmful environmental exhaust emissions of motor vehicle’s combustion cycle by-products. Its function is to chemically change harmful pollutants that the engine has combusted in the process of its various starting, driving, power and idle conditions. These pollutants include carbon monoxide, hydrocarbons, nitrous oxides, etc. A catalytic converter chemically changes these into harmless substances like carbon dioxide, nitrogen and water vapor. The catalytic converter uses an inside structure called a substrate. This is a ceramic or stainless steel monolith block that is covered with precious metals such as platinum, palladium and rhodium. The monolithic block consists of many fine channels, which are covered by a coarse wash coat above which the catalytically effective precious metal layer is placed. It is these elements, which cause the chemical change. For a catalytic converter to last in normal vehicle service operation, it is essential the engine, its ignition system, fuel system, and emission devices must all operate within manufacturer specifications properly, consistently, efficiently and correctly at all times.
If the catalytic converter you replaced or are about to replace was damaged or destroyed by the melting of the ceramic monolithic structure or the metallic substrate, it means that excessive amounts of liquid fuel particles reached the catalytic converter substrate. When this occurs, it raises temperatures, causing the substrate to exceed its fusion point of around 1,500 degrees Fahrenheit, thus harming the substrate.
