Audi Catalytic Converter Customer Reviews

Came very fast. I ordered it round a lil before 1 on a tuesday and it was at my house friday morning. It was the right part and the price was way less than if I had bought it from a local auto parts store. Two things to know; you need to be sure everything that caused it to go bad has been fixed, if not you will eventually kill the new one, so get your check engine light off first. Clean out your egr valve if you didn't need to replace it, might as well replace your pcv valve cuz its only $3 and clean out the area where it's seated, and if an O2 sensor is bad replace it, the only two on this car (2000 model year) are right in the area of catalytic. Also if your flex pipe is bad, you can just a flex pipe, so you may be able to piece it together without having to buy the converter with the pipe to manifold. I ended up replacing or cleaning almost my whole emissions system to get it to pass the state test. With the help of this site and my own ingenuity what would have been over $500 in parts cost less than $140, not bad at all!!
Purchased on Jan 27, 2014
looks to be a quality item. unfortunately not the one i needed as it didn't have the connectors on each end to hookup to my exhaust manifold and then to the y-pipe.

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.
