If you own a car, you might be wondering, how many catalytic converters are in a car?
Catalytic converters are a necessity as they reduce emissions and increase your engine’s lifespan.
In this article, we are going to answer some of the questions you might have about a car’s catalytic converter, such as how many catalytic converters are in a car, where it is located, how you can tell if it’s bad and lots more.
Read on!
How Many Catalytic Converters Are in a Car
Most cars have one catalytic converter, at least. The number of catalytic converters in a car depends on how many exhaust pipes the car has. If it has a dual exhaust system, it’ll have two catalytic converters, one for each exhaust.
After 1975 with the new pollution control laws, converters for diesel were first introduced to cars. A catalyst converts harmful pollutants to ones that are less harmful before they leave an engine’s exhaust system.
Water vapor, nitrogen, and carbon dioxide are all produced as by-products of the burning of fossil fuels.
While water vapor is harmless, both nitrogen and carbon dioxide have been known to contribute to what is commonly referred to as “global warming.”
Other harmful gasses can be created during the combustion process due to various inefficiencies. For example, smog and acid rain are also primarily caused by nitrogen oxides, which are smog-causing substances.
Carbon monoxides are colorless, odorless, and poisonous gases; in addition, certain volatile organic compounds such as hydrocarbons can be released from fuels that haven’t been burned sufficiently.
They’re said to contribute to ground-level ozone pollution or “smog” when present in large quantities.
Modern vehicles are equipped with three-way catalytic converters that reduce the three main pollutants resulting from combustion.
Catalytic converters reduce pollutants in two stages. The first reduction catalyst reduces nitrogen oxide emissions, and the second stage oxidation catalyst reduces hydrocarbons and carbon monoxide.
Bad Catalytic Converter Symptoms
Below are some bad catalytic converter symptoms
1. Illuminated Check Engine Light
If your check engine light or dashboard illuminates, you have a faulty catalytic converter.
When a car is malfunctioning because of faulty emissions, the computer will always try to locate the problem and display warning messages on your dashboard.
You need to take your car to a mechanic right away in order to find out what needs repairs so that everything goes back to normal.
2. Increased Vehicle Emissions
When your catalytic converter is not functioning properly, this can cause your vehicle to fail an emissions test if the engine is producing excessive carbon monoxide.
In addition, a malfunctioning catalytic converter may need replacing or could be inactive from its hot or prolonged fuel exposure.
Your mechanic will advise you on the cause before deciding on the best course of action for having the part replaced.
3. Reduced Engine Performance
When your catalytic converter is clogged, your car will not maintain speed while you’re driving.
You’ll notice that the RPMs in your car will increase slightly at an earlier point of acceleration than before, which could be a sign of a faulty catalytic converter. Take the car to a mechanic to have it checked.
4. Poor Fuel Efficiency
The fuel economy can be significantly reduced when a catalytic converter is clogged, especially when driving down the highway.
However, any leaks in this area might harm the fuel efficiency because there will be less back pressure, resulting in less ability for take-off.
Because the weaker emissions are not accompanied by adequate travel resistance, they consume more fuel over time and may reduce your mileage if not detected at an early stage.
However, a problem anywhere along this area can seriously impact the performance of your engine. Thus it should be thoroughly checked from time to time by a professional mechanic.
An improperly functioning catalytic converter may cause your vehicle to get worse fuel mileage than usual. If this happens, you must get it checked immediately by a mechanic.
5. Strange Smell From Exhaust
The car is acting very oddly – it runs rough and emits an exhaust smell. The smell is caused by a buildup of fuel, which prevents sparks from igniting properly. This can result in burnt oil or rotten egg odors.
It could also mean that your car simply isn’t getting the fuel it needs to function correctly, so make sure you talk to a mechanic about whether or not you need a new catalytic converter.
What Could Damage a Catalytic Converter?
The catalytic converters in your car are likely to wear out over time. The manufacturer’s maintenance schedule outlines when the catalytic converter needs replacement in most new cars.
However, many people disregard it due to the high replacement cost.
Catalytic converters can also be damaged by misfires, clogged crankcase ventilation, or worn piston rings, which lead to more frequent combustion of motor oil in the engine.
The honeycomb could also be damaged when the head gasket fails and coolant is introduced to the combustion chamber.
Catalytic Converter Location
The catalytic converter is installed between a car’s mufflers and exhaust pipe manifold. Depending on the type of car you drive, the distance of the catalytic converter from the engine may vary depending on how old or new the vehicle is.
Meanwhile, some engines have the catalytic converter installed in their exhaust manifold; others may install it inside the exhaust tube.
Catalytic Converter Replacement Cost
catalytic converter replacement costs range from $945 to $2475, including labor and parts. When dealing with vehicle emissions testing or repairs, it is recommended that an expert be consulted to not cause any other problems.
Sometimes newer models will have an emissions warranty (EPA). However, if it’s determined that the part needs to be replaced, it would be worthwhile to consider simply replacing the part instead of repairing it.
Since many people who decide to go through the hassles of getting their catalytic convertor repaired find themselves burning out due to a lack of experience in performing such tasks on their own.

Frequently Asked Questions – How Many Catalytic Converters Are in a Car
Can a Car Have Three Catalytic Converters?
Catalytic converters reduce the emissions produced by internal combustion engines. Most cars come standard with one catalytic converter, but certain cars have multiple catalytic converters to meet emission regulation standards.
Do All Cars Have Two Catalytic Converters?
No, Many cars have only one catalytic converter, and you’ll likely need two if your car has dual exhaust.
Can a Car Have Four Catalytic Converters?
A car can have up to four catalytic converters, but this is only the case if it is breaking laws relating to pollution. Catalytic converters are a crucial component of your car’s exhaust system. Some cars possess multiple catalytic converters to meet emission regulation standards.
Why Do Cars Have Two Catalytic Converters?
Exhaust systems are almost universally installed in cars. Essentially, they are a system of pipes designed to direct exhaust fumes from the engine’s combustion. Two catalytic converters are placed on these pipes on dual exhaust systems to neutralize each set of emissions that comes out of all the pipes.
How Can I Tell How Many Catalytic Converters I Have?
Most cars have only one catalytic converter. However, if your car has a dual exhaust system, you will need two catalytic converters. The number of catalytic converters a car has mostly depends on the exhaust system.
What Does a Secondary Catalytic Converter Do?
The first converter reduces carbon monoxide and other harmful gasses, whereas the second simultaneously filters out any small particles in the exhaust released from the first. In addition, the fluid or liquid created by this combination of process steps helps reduce other harmful gasses previously released from the exhaust.
How Many Catalytic Converters Does a Ford Mustang Have?
It has two catalytic converters. You will find a catalytic converter on the driver’s side of the Ford Mustang in the exhaust manifold and another on the passenger side.
How Many Catalytic Converters Are on a Mercedes Benz?
New cars generally will have one or two catalytic converters, including Mercedes, which does a wonderful job stamping their serial number on each unit. Having several serial numbers listed simultaneously makes it easy to identify them as OEM units.
How Many Catalytic Converters Are on a Ford F 150?
The Ford company has placed dual-system catalytic converters on the back and front of its sports utility vehicle, the Ford 150. These converters are made to help better control emissions in accordance with the more stringent pollution control standards.
How Many Catalytic Converters Are in a Chevy Silverado?
All Chevrolet Silverado models have a catalytic converter attached in front of their exhaust pipe assembly.
