Mercedes Benz 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.

Mercedes Benz Catalytic Converter Articles

Nowadays, it is indeed important to have vehicles that will transport you from places to places and at distance you intend to be at a given time. And it's a common knowledge that thousands of vehicles are running around the globe each day; thus, these thousands are contributing everyday to pollution. Good thing nowadays, the automotive industry is aware of their responsibilities to the community. Innovations and modern technology has introduced techniques to prevent vehicles or even just to minimize their emission of harmful elements contributing to pollution. Aside from such techniques, laws and regulations regarding the problems of pollution were introduced; these stated standards on emission controls. Hence, catalytic converters became a vehicle's standard part. Vehicles like Mercedes Benz are required to have one or two catalytic converters; thus, reliable Mercedes Benz catalytic converters are standard with every Benz.
 

Considering the effect of having one, catalytic converter is one innovation that had helped a lot in emission problems. Before catalytic converters, are lots of other techniques to lessen the effects of vehicle emissions; auto manufacturers and engine makers have made ways to convert elements from engine's combustions into less harmful elements. Nowadays, performance quality catalytic converters are all you need. These performance parts help clean the gases produced by your vehicles as it burns fuel when operating. They help control harmful gas emissions from your vehicles like hydrocarbon, carbon monoxide and nitrogen oxide. More often, catalytic converters are installed between the exhaust manifold and the muffler and it uses chemical that act as catalyst.
 

Generally, catalytic converters work in three stages; these include the reduction catalyst, oxidization catalyst and the control system. It is important that you choose the kind and type of catalytic converters that you're going to get for your vehicle as there are varied choices available. You can choose a high flow catalytic converter or a performance catalytic converter; whether you choose the high flow or the performance type, be sure it matches the specifications of your vehicle and its engine components. Also, make sure that your catalytic converters don't have any problem and are functioning properly to ensure proper overall performance.

FAQs—Mercedes Benz Catalytic Converter

Can I use an aftermarket converter to replace a defective converter on my California-registered Mercedes Benz that has OBD II?

Yes. Just make sure the replacement is approved for use on your Mercedes Benz by the California Air Resources Board (CARB). To be more specific, check the specs and information on the converter to find out if it 's listed for replacement on a specific make and model of vehicle with a particular engine size. This info should be available on the application catalog of the device 's manufacturer. The catalytic converter should also possess the E.O. number and various important markings on its body. For example, AirTek, Inc. got D-280-80, D-280-79, D-280-77, and D-280-73 as the E.O. numbers issued for its converter line by CARB.

Can a good catalytic converter or pre-catalysts be removed from a Mercedes Benz?

If the converter is good or functioning, you 're not allowed to remove it from your Mercedes Benz (or any other vehicle make and model). Any technician who 's caught doing this will be considered doing a violation that could cost him a $2,500 fine for every time he does it. Even DIY motorists will be subjected to fines if they remove their operational converter. In turn, pre-catalysts shouldn 't be removed either unless they 're defective. They should be treated like any other converter. Eliminating your pre-cat is only allowed when the main and pre-cat converters have gone bad. Otherwise, you 'll also be fined for removing it.

Can I replace two converters with one aftermarket converter or install duel exhausts on my Mercedes?

One aftermarket converter can replace two converters provided that the replacement unit has been approved by CARB and it 's used according to the instructions of the aftermarket convert manufacturer. However, installing duel catalysts or exhaust on your Mercedes Benz is a no-no. Your vehicle should instead have a dual catalyst or exhaust configuration included by design. According to the Environmental Protection Agency (EPA), you can 't upgrade to a dual to replace your existing catalytic converter unless you were to dual an exhaust system behind said converter (which is the loophole most vehicle customizers use to get the customization they want without breaking the law).

Can I replace a two-way converter with a three-way converter?

Yes, you can. However, you should make sure the three-way converter has been tested for your catalyst type by the manufacturer, which is in compliance with the aftermarket converter procedures outlined by EPA. Don 't forget to do the following. Incidentally, a two-way converter is called as such because it handles two simultaneous tasks, which is the oxidation of hydrocarbons to carbon dioxide and water and oxidation of carbon monoxide to carbon dioxide. Meanwhile, a three-way converter is responsible for simultaneously oxidizing unburnt hydrocarbons to carbon dioxide and water, oxidizing carbon monoxide to carbon dioxide, and reducing nitrogen oxides to oxygen and nitrogen.

How do you determine what universal converter to use?

Aftermarket universal converter installation (for the sake of replacing a bad converter) entails meeting the emission requirements of your Mercedes Benz. Thusly, these devices cannot be chosen based on their size alone. You should look up the catalog of the website selling you the converter or ask for the papers of the converter from a brick-and-mortar seller in order to find the recommended universal converter for your vehicle that has the right loading. There should be some universal converter specifications guidelines included with every aftermarket converter purchase. Otherwise, that converter is not worth your time.
