Audi Catalytic Converter Customer Reviews

Was a bit bigger than the original but with extra work did work.
Purchased on May 29, 2015
Great product. OEM quality at 1/4 the price of OEM from dealer. I would recommend using OEM gasket instead of the one that is included. It will work, but I felt more comfortable using the factory one.
Purchased on May 29, 2014
Buy it. It works, fitment no problem. The beat thing no CEL light. you can't go wrong..

Audi Catalytic Converter Articles

The Audi catalytic converter is an extremely important component in today's vehicles, helping to reduce the pollution emitted through the vehicle exhaust system to pass into the air we breathe. The engine combustion process produces several chemicals that can be harmful to the environment. Among these are carbon monoxide, which is a gas that has no color or odor, and is extremely poisonous to humans, nitrogen oxides, which contribute to acid rain and are an irritant to mucus membranes, and hydrocarbons that are a byproduct of the evaporation of unburned fuel and produce smog. The Audi catalytic converter is designed to sift out a large portion of this pollution before it reaches the outside air to contaminate our environment. The Audi catalytic converter does this using a ceramic structure with a honeycomb design that is coated with two different metals that act as a catalyst, creating a chemical reaction that either traps or burns some of the molecules of these pollutants as the exhaust fumes travel through. The most common metals used in the Audi catalytic converter are platinum, rhodium and palladium, which are the most efficient catalyst metals for reducing these toxic emissions. The catalytic converter is quite efficient, reducing the amount of pollution that is emitted into the air as we travel, more important than ever with the continuously increasing numbers of vehicles on today's roads, and the strict emissions standards in effect in most areas to keep our air clean. We carry a selection of quality Audi catalytic converter replacements in our online catalog, all at great prices. Our secure site makes ordering your Audi catalytic converter safe and efficient or, if you prefer, our toll-free phone line is just as convenient.
