Before settling on which catalytic converter is best for you, it is imperative that you do your research because there are several different factors that you have to consider before you reach a decision.
Taking these factors into account will not only save you time but will also streamline your choices to some degree, which will ultimately make it easier to choose a product that suits you the best. Therefore, let’s jump into this before we digress!
Check for Two-way/Three-way Functionality
Now there are two main types of catalytic converters on the market, namely, Two-way converters and Three-way converters.
The Two-way is your standard catalytic converter while the Three-way has the added function of controlling the emissions of nitrous oxide that is highly toxic and harmful to the environment.
Therefore the best course of action is to consider both options as well as the emission laws in your state or area to decide which one will be better for you.
Before you decide on a particular catalytic converter, it is integral that you check if it is even compatible with your car.
For this purpose, it is recommended that you double check every model with the year of release, as well as the make and model of your own car. In addition, it is important to check the level of emissions your car produces.
If the catalytic converter you choose is compatible with controlling them according to state laws.
Vehicles have different levels of emissions depending on where they were manufactured and their respective models etc. Therefore it is important to gauge the kind of converter grade that your vehicle qualifies for.
For instance, most catalytic converters come with two different options. In this case, it is recommended that you keep tracks on the level of emissions produced by your car.
In addition, you can consult your local mechanic in order to decide which grade you should be buying.
Another thing to consider is whether you should be purchasing a universal fit catalytic converter or a direct fit converter.
The Direct fit model of course can fitted directly to your vehicles without any additional welding etc, while the universal fit model do require some work. Both can be fitted on your own, although you will extra materials for the latter.
Both designs have their pros and cons and it is better to consult a professional to decide which model will work better on your car specifically.

Frequently Asked Questions
Before going ahead and investing in a catalytic converter, you probably have some questions that need to be answered before you can settle on a decision.
Hopefully some of the following FAQs will play a part in satisfying some, if not all, of your queries.
- What do catalytic converters do?
- What are catalytic converters made of?
- What is a catalytic converter worth?
- What metal is in catalytic converters?
- What is the scrap value of catalytic converters?
- Do Tonneau Cover Save GasInside a catalytic converter?

- Do test pipes replace catalytic converters?
- Do motorcycles have catalytic converters?
- Do I need to replace both catalytic converters?
Vehicles produce a fair amount of toxic gases that can be harmful, bordering on fatal, if released untreated to the atmosphere. Therefore, catalytic converters are fitted in vehicles to convert these toxins into harmless gases.
Catalytic converters are usually made up of some form of metal. Most commonly you will come across stainless steel construction for the outer body with Aluminum coating on the inside for durability.
The worth or value of a catalytic converter can vary depending on the amount of precious metals that are inside the converter itself. This is of course vastly different for different models and manufacturers.
The most renowned metal in a catalytic converter is Platinum, which acts the catalyst itself. Additionally, you can find rhodium, copper, palladium, and iron in there as well.
Once again, the scrap value of a catalytic converter depends on the model, size, age and condition of the converter. Typically scrap parts range anywhere from around USD 50 up to USD 120 or more.
There is a honeycomb type structure made of precious metals. It is on this surface that the catalytic reactions take place to turn toxic exhaust gases to harmless emissions.
Yes, all kinds of vehicles have catalytic converters. For diesel cars in particular, it is typically known as a Diesel Oxidation Catalyst or DOC for short.
If you’re in a pickle and looking for a quick fix then yes, straight test pipes can replace a catalytic converter. However, that is not a permanent solution and a converter needs to be replaced as soon as possible.
Although they are not easily visible, most motorcycles do have catalytic converters. However, there are some exceptions but the numbers have greatly reduced since emission laws have become stricter.
Most cars come with only one catalytic converter but there are some who have two. The second one is more of a backup, however, if anything goes wrong, it is best to consult with a mechanic before you go and spend hundreds of dollars replacing both converters.
Now as we reach the end of our reviews, you probably feel much more at ease regarding the prospect of buying a catalytic converter.
Since this is an important component of any vehicle, you cannot do without it. Similarly, you need one that you can use for the long haul without it being too much of a burden on your budget.
