If you’re driving a car, chances are, you know what a catalytic converter does. Yes, it’s one of those things that many of us have learned about in science class.
It converts oxides of nitrogen and carbon monoxide into carbon dioxide and nitrogen. Carbon dioxide is only a pollutant in high concentrations, and it’s far better than carbon monoxide.
So you should be using one. Given the situation of the planet right now, it’s honestly a must-have. The best catalytic converter offers top-notch service and cleans the environment as well.
That’s why we are writing this review to help you find your perfect catalytic converter.
Best Catalytic Converter Reviews
Now you might be confused. That’s because there are so many options in the market. But worry not. We are here to help. Here are our recommendations.
1. Eastern 70318 Catalytic Converter
I suppose, one of the most important things that people look for in a particular product is how easy it is to install. If you’re that type of person then you’re in luck; this is precisely that type of product. This catalytic converter is pretty much a plugin. You need fundamental skills to operate them. Anyone can strap them on.
This could also be the thing you’re looking for if your vehicle is on the lower side. Most vehicles do have a converter equipped, but over time it gets less and less efficient, and that strain falls on the engine of the vehicle.
The engine might even fail altogether. With this, however, you can run the vehicle for a couple more years with ease. The reason behind this is that it has excellent airflow. The airflow causes stress on the engine to get significantly reduced.
Old converters usually strain on the engine for the same reason. It gets clogged, and the engine needs more and more power to push the exhaust gases outward. With proper airflow, this can significantly be reduced.
All of this makes this car part an excellent replacement catalytic converter. On top of those unique benefits, it can fit into a wide range of vehicle models. This versatility gives you the option to get it for your car or truck, no matter how obscure it might be. Therefore, you can gain a few more years on your vehicle before you scrap it.
This instrument offers all of these, but at a very reasonable price. Yes, this is a budget catalytic converter. Therefore, it is affordable by almost anyone.
If you’re rich enough to afford and maintain a car or a truck, you’ll be able to get this. It’s going to make the smallest dent in your budget; moreover, in the long run, you’ll save money.
- Quick install
- Good replacement part
- Excellent airflow
- A bit inefficient
2. EvanFischer REPG960301 Silver Powder-Coated Catalytic Converter
If you’re looking for a replacement, your search might be over. That’s because this model, manufactured by Evan Fischer, is made keeping that precisely in mind. At its core, it is a replacement part. Therefore, it has to be versatile. Without that, it’s useless. It’s perfect and fits well with almost any tailpipe.
As it is a replacement part, you might think that it may have trouble adjusting to your car. Perhaps your car isn’t the most common. That’s okay. It’s not a problem for this thing at all. Its performance is one hundred percent, in any setting. The exhaust is molded around and forced through it for forceful conversion.
The instrument is packed with the catalyst that converts carbon monoxide and nitrogen oxides into nitrogen and carbon dioxide. Its layout allows for effective catalysis. It’s made to ensure that the maximum surface area is exposed to the emitted gases. This leads the final emissions being almost entirely converted.
However, as the air is forced out, and is made to go through every nook and cranny of the pipe, it can lead to blockages. This is mainly a threat if your car engine is old.
Old engines tend to pump out more soot, which causes blockages. They also tend to be affected by obstructions. Make sure to clean regularly.
Nevertheless, the other perk it has is that it can be installed quite fast. This makes it a convenient replacement as well. You could be out on a road trip and if your engine fails, and the converter is the issue, you can just set this up and be on your merry way. The smooth and fast installation is always a big plus.
- Can be installed easily
- Effective emission
- Excellent replacement
- Prone to blockages
3. MagnaFlow 93419 Direct Fit Catalytic Converter
Faulty converters or even just tailpipes in general, can the bane for old engines. Now, there are a plethora of reasons why you still run one. Perhaps you can’t afford a replacement right now, or you’ve gotten a bit attached. Whatever the reason may be, you should consider this instrument. It’s quite easy on old engines.
On top of being easy on the engine, it’s also an excellent fit. In a way, it’s a crutch for an ailing engine that’s on its final years. It can extend its lifespan. It fits rather easily on the back of almost all vehicle types that employ a similar kind of tailpipe. This instrument doesn’t discriminate at all.
Perhaps that is the reason it is so easy to install. They say that over time you get the hang of using a vehicle and you are slowly familiarized with its ups and downs. However, with this, you don’t have to go that far. Even if you got your license yesterday and only have the necessary DIY skills, you can fix this on.
Unlike many replacement converters, this will last you for years. It’s almost like strapping on a brand new engine. Of course, that is only how it will feel. The engine will give away at some point. However, you can be sure that it won’t die because of pressure from the exhaust. The converter will outlast the engine.
The one downside to this, unfortunately, is that it can be very noisy. I guess all that high gear performance comes at a cost. This can put you off, especially if you’re a country driver. I understand. In more urban areas, it’s not usually a problem though, as it can easily blend in with the miscellaneous noises of the big city.
- Easy on old engines
- Fits well
- Easy installation
4. AUTOSAVER88 ATCC0007 2.5″ Inlet/Outlet Universal Catalytic Converter
Designed and developed by AUTOSAVER88, this model might be what you’re looking for, particularly if you’re trying to save a couple of bucks. This is an excellent budget pick. Don’t think that it’s bad just because it’s cheap! It can be more than only capable of performing as an excellent catalytic converter.
Installing it can be a little trouble, as you need to get your hands dirty and weld it onto the tailpipe. However, you need not to worry. The metal on this is soft and comfortable, so you can easily fit it on even if you know the most basic welding skills.
If you have the DIY skills, setting it up is so easy. The chances are that you can do some welding, given that you own and maintain a car. And, even if you can’t, learning to do so is quite easy. You can take help from the internet. But be careful, welding involves high temperatures and can be quite risky.
It also boasts quite a few extra features. One that deserves to be talked about is the inclusion of an oxygen indicator. The indicator measures the oxygen levels inside and outside of the vehicle and acts as a sort of warning system to let you know when the engine isn’t getting enough oxygen to burn fuel.
This converter is for anyone who is more of an outdoorsy person. That’s because it’s geared for jeep or ATV exhausts. Those vehicles burn a slightly different fuel sometimes and thus have a different type of exhaust. This converter, thanks to its good airflow and exceptional versatility, can give you a smooth ride on a road trip.
- Suited for jeeps or ATVs
- Has an oxygen sensor
- Easy to install
- May not be suitable for road vehicles
5. Walker 15036 EPA Certified Standard Universal Catalytic Converter
Like any replacement part, this is something that’s nothing short of amazing. It can do its job marvelously. It has a sort of general-purpose shape that lets you seamlessly fit it onto nearly any pipe. On top of that, it can perform well no matter what type of car you fit it on, making it quite versatile.
This virtue of being such a suitable replacement makes it ideal for older engines. Once you fit it on, it’s almost as if the engine is good as new.
It seems to revive old engines in a way that those would otherwise huff and puff and struggle to run with the old converter on. This reduces stress and lets your engine work like new.
The interior of the tool is well designed as well. All of it is made to restrict the flow of any fluids. Faulty or poorly performing converters may leak. This causes exhaust to bleed out without getting converted. It can also leak water that has condensed in the pipe. That’s why, tight, leak-free converters are the key here.
While it prohibits any sidestepping, it is very supportive of the forwarding flow of exhaust gases. That’s because the conversion can only happen then. What I’m trying to say is that the airflow is top-notch. There is little chance of any blockage happening, therefore, it also puts very little strain on the engine.
There is a single issue that prevents this from being perfect; it’s that installing this instrument is difficult. It takes a lot of time, and you need a seasoned hand to do it correctly. If you’re new, I suggest leaving it to the mechanic because if you fit it incorrectly it can put the engine of your car at risk; or worse, cause an accident.
- Good for old cars
- Works excellent as a replacement part
- Smooth airflow
- Difficult to install
6. Catalytic Converter w/Exhaust Manifold for 04-08 Chevy Malibu
Again, another product by AUTOSAVER88, which is quite easy to work with. By that, I mean that it is incredibly easy to install. Even if you don’t have prior work experience with these types of things, installing this won’t be an issue at all.
And, being a car owner means that you have at least rudimentary knowledge, and that’s enough.
You could have just about any car, and you would still be able to fit this on easily. Yes, the usual procedures are still needed to install this, but since it is so easy to fit, the time and effort that is spent on it is significantly reduced.
This makes it extremely convenient. It works on regular road vehicles as well as off-road vehicles.
It’s so versatile that it can be used both as a replacement part and also as a brand new tool. If you’re running an automobile industry, you should consider this as an option. It assembles well onto a new car. On old cars, it’s a significant replacement part that fits neatly like a glove.
On the topic of old cars, let’s talk about how great this model of a catalytic converter is for them. Old vehicles usually harbor old engines, and those come with a host of issues.
One of the biggest of those is that the tailpipe converter becomes clogged and puts pressure on the engine. However, with this, you can easily prevent that.
When it comes to additional features, this boasts two of those. An oxygen sensor that monitors oxygen in and out of the engine, and an engine sensor that makes sure that the fuel ratio and air ratio remain balanced.
If there are any issues, they will go off, and you can then stop to check under the hood. It can be a lifesaver for your engine.
- Engine sensor
- Functions as both an independent and a replacement part
- Simple design
- A bit expensive
7. TED Direct-Fit Catalytic Converter
One of the defining features that this engine boasts is an oxygen gauge. It works by employing electrodes in and out of the engine. An absolute difference in oxygen creates a potential between the electrodes and therefore causes detection.
The sensor on this particular one is quite sensitive and starts detecting at very slight variations.
Even with those ultra-sensitive detectors, chances are, you will rarely detect an oxygen imbalance. That’s because the airflow on this is excellent. It is incredibly efficient and steers all the air outside.
In fact, the catalysis process does little to hinder the flow because the catalyst is set in a way so that it will minimize airflow restriction. The excellent airflow, coupled with those highly sensitive sensors gives this machine the ability to improve upon the lifespan on an old engine.
Yes, you can take out your old rusty for a couple more rides before you have to dump it in the junkyard. That’s because this tool dramatically reduces the strain that an old engine might have to face from cloggy tailpipes.
It is the best catalytic converter for performance as it has an extremely efficient system to sift out the pollutants and convert them into something less harmful. Almost a hundred percent of the nascent carbon monoxide and the various oxides of nitrogen are safely converted to carbon dioxide and nitrogen.
While it is made for Corolla models, it can work for similar types of cars as well. This makes the product a rather adaptive option for you. All models of the Corolla type fit exceptionally well, but I guess the more coveted feature is that it can slightly be adjusted and welded onto just about any similar kind of car.
- Good fit
- Sensitive oxygen detector
- Thorough airflow
- Excellent catalysis
How to Choose the Best One
Here, we are going to go over the factors you need to consider before making a decision.
This is arguably the essential aspect of a catalytic converter. Check for the catalyst used and the layout of it as well. Make sure that it encompasses the maximum surface area. You should take into account how much of the exhaust is converted into safer gases. That’s the whole purpose of getting a catalytic converter.
While no converter can reliably convert all of the gases, a high percentage should be a prerequisite. You should settle for something that can easily sustain about eighty percent conversion with relative ease. Do not get something that has under seventy percent conversion.
You should keep an eye out for that, especially if what you’re running is an old engine. Old engines receive a lot of stress from airflow issues. These issues can be minimized if you get a converter that can guide air out with the little issue.
Often, a catalytic converter builds obstructions in it over time. Make sure you get one that has the least tendency to do so.
However, it should be noted that increased airflow comes at the cost of effectiveness. The faster the air flows over the catalyst, the less of it is converted. This can be balanced by running the gas through the maximum surface area of the catalyst.
Be careful about getting a “super smooth” model unless you don’t mind polluting the environment.
Again, this is another crucial factor to consider. Imagine buying a catalytic converter that fits like a glove on your vehicle now, but then you decide to change your car.
Are you gonna buy a new one?
Now, a catalytic converter can be reused, but only if it’s versatile. Otherwise, you won’t be able to use that and will have to get a new one.
Finally, let’s talk a little about the last things you should be looking into. Everyone wants their product to last. And this applies here as well.
While most converters last quite
well, only the best catalytic converter will stand the test of time enough to
be able to outlast the vehicle itself. This is more common in older engines,
but if you get the right one, it can survive a brand new car.
Frequently Asked Questions
Q: What if I have an offroad vehicle?
Ans: Good question. ORVs and ATVs have the issue that they often burn diesel or some other fuel. However, don’t worry, as this list has converters suited for that.
Q: Can I fit it onto a non-recommended model?
Ans: Usually, yes. But some converters are oddly specific. Look out for that when you buy.
Q; Is it safe for large vehicles?
Ans: There are many that are designed for large vehicles. You have to keep an eye out for that.
Q: How do I know that it’s working?
Ans: You can pedal the gas and have someone take a look. The exhaust should be clear. If it is brownish, that means that it’s nitrogen dioxide, and therefore it’s not working.
Q: How long does one last?
Ans: With old engines, it can easily outlast them. A good one can even hold out until the end of a new vehicle.
