BMW 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.

This product got me out of a jam. Saved me $1000 and passed inspection.

BMW Catalytic Converter Articles

Very few people notice that it is warmer in countries with wide open spaces than in cities. This may be because of the buildings and skyscrapers that fill these places, structures that are nonexistent in those with grass fields and meadows. This claim has actual basis because the buildings and skyscrapers themselves act as structures that shade everyone from the harmful rays of the sun. This is a good thing and is beneficial to the inhabitants of places such as these, because they are kept out of the sun's reach by these structures themselves.
What other people do not know is that buildings and skyscrapers are not the only ones which protect them from the ultraviolet rays of the sun - there are also the thick clouds of smoke and fog that proliferate in the atmosphere. Because they act as barriers that block the heat of the sun, one might say that this is beneficial - and it is, too. The problem is that they add up to the dirty air humans have to breathe in everyday to be able to survive.
Air pollution is caused by many factors, but it is, at most, caused by all the gases that come out of each and every kind of vehicle that roams the planet. There was a time when vehicles, because they soil the air, were considered a threat to the environment. The reason why vehicles have ceased to be so is because they have employed catalytic converters that would process their by-products before being released into thin air.

Those who own BMW vehicles have no worries about abusing Mother Earth. This is because the catalytic converters they employ are serviceable enough to be able to do their jobs well. BMW catalytic converters are efficient enough to help reduce air pollution to a minimum. These they do by oxidizing destructive chemicals, making them safe enough not do the environment harm.
People can build all the skyscrapers they want, but they can surely do without pollution. The BMW catalytic converter is the solution that can eliminate this problem once and for all.

Closer Look at BMW Catalytic Converter

In order to comply with today's strict emissions laws, your BMW has a full system to reduce the amount of pollutants that your vehicle releasers into the environment. One of the most important parts of this system is the BMW catalytic converter. Even the most modern of today's engines remains inefficient due to the nature of the internal combustion process, and some of the fuel escapes intact into the exhaust stream. The BMW catalytic converter is in charge of burning this fuel further, because if it were allowed to exit into the air, it would have serious consequences to the environment. By using a small amount of platinum, the BMW catalytic converter starts a chemical reaction that further burns the fuel, though the energy is largely wasted from this reaction. To monitor the efficiency of this process, the vehicle has an oxygen sensor installed after the BMW catalytic converter. If the sensor detects too much oxygen in the exhaust, then the engine's computer will attempt to correct the problem by changing the amounts of fuel and air in the combustion chamber. If the computer cannot fix the problem, it will illuminate a light on the dashboard, which will indicate that there is a problem with the BMW catalytic converter. The most common cause of a failure in this part is severe corrosion, much like the rest of the exhaust. When you need to replace the BMW catalytic converter, you will find the correct version for almost any vehicle in our large online catalog, for a great price. To order the BMW catalytic converter, you may do so through our secure web site, or by phone, with a toll-free call.
