How Many Catalytic Converters Are In A Ford Mustang?

You’ve recently bought your dream car: the Ford Mustang, and now you’re getting ready to bring it home.

Before you do, you have to do a little research on How Many Catalytic Converters Are In A Ford Mustang?

Many people don’t know that there are various catalytic converters and that they all fill various needs.

Some of them may be dangerous whenever left alone or tampered with incorrectly.

How Many Catalytic Converters Are In A Ford Mustang?

So, How Many Catalytic Converters Are In A Ford Mustang?

The answer relies upon the year and model of your vehicle, yet there’s always over one present in all models.

A couple of them may even be pre-catalytic converters that convert harmful chemicals into less harmful ones, which then, at that point, get converted by the main catalytic converter.

Like the exhaust framework on your 2003 Ford Mustang with the 3.6L v6 engine first. From the factory, you have four catalytic converters and four oxygen sensors (o2).

What Is Catalytic Converter?

A catalytic converter is a portion of your exhaust framework intended to diminish emissions. It looks like a small suppressor on the outside, yet the inside structure makes it extraordinary.

There, you’ll find a honeycomb network coated in precious metal intended to maximize the surface area so that gas will interact with the catalyst. As exhaust passes through, harmful gasses are separated into less harmful ones, thus the word converter.

Catalytic converters are divided into two types. A two-way catalytic converter is one type, while a three-way catalytic converter is another. The names show how many functions these converters can perform.

Carbon monoxide is split into carbon dioxide and oxygen by a two-way catalytic converter. Second, harmful hydrocarbon gases are broken down into carbon dioxide and water.

The three-way catalytic converter diminishes nitrogen oxides into nitrogen and oxygen, converts carbon monoxide into carbon dioxide, and third, hydrocarbons into water and carbon dioxide.

What Precious Metals Are in Ford Mustang Catalytic Converters?

Because of the precious and expensive metals used in these converters, catalytic converters are extremely expensive to scrap.

Most of the metals are recoverable and can be sold at current prices that are higher than their initial prices.


In catalytic converters, metals like platinum are used. It is critical to filter harmful gases before they are released into the atmosphere. Platinum oxidizes and neutralizes carbon monoxide, the gas that depletes our ozone layer.

The price of platinum varies widely, but the overall cost graph has soared. Although the amount of platinum in catalytic converters varies by vehicle, most of them contain between 3 and 7 grams.


Another precious metal found inside a catalytic converter is palladium. It channels harmful gases, such as hydrocarbons and carbon monoxide, by removing the harmful components of these gases, similar to platinum.

Palladium is a metal that is more valuable and expensive than platinum. That you can only find inexpensive extravagance cars is more of an extravagance thing.


Rhodium is the third most expensive metal in the catalytic converter. It also catalyzes the harmful substances in the emitting gases, which allows it to control and sift them through.

Rhodium, like the other two metals, is recoverable and can be sold at a high price. The amount of this metal in Ford car models is approximately 1 gram.

Metal Foil Or Ceramic Foil

The foil is a roll-like outer design you can see, and it contains the above precious metals. Metal foils are made of stainless steel, and it is a productive material to use in the converters.

Ceramic foil is another sort of foil used in these converters. Other metals are stirred up with the ceramic in this kind of catalytic converter. These two materials are worth not exactly the other metals yet good enough to profit from scrap.

How Does A Catalytic Converter Work?

Three pollutants-nitrogen oxides, hydrocarbons, and carbon monoxide are converted into harmless water and carbon dioxide by a three-way catalytic converter.

Nox is created when the combustion chamber’s consumption temperature transcends 2500 degrees Fahrenheit because the atmosphere is 78% nitrogen and 21% oxygen.

Whenever atomized hydrocarbon fuel is touched off in the combustion chambers, it super-heats the nitrogen, causing it to expand.

During times of combustion, this drives the piston. At high temperatures, however, Nox is formed when oxygen binds to nitrogen.

Exhaust gas recirculation (EGR) is an emissions framework component that once again introduces some inert Sans oxygen gas to the intake stream while the vehicle is above inactive. This cools the combustion consumption to forestall Nox.

As for the hydrocarbon (HC), each molecule of HC wants to get “married” to two molecules of oxygen when the spark happens. Uniting the oxygen with the carbon happens when the spark sets off a combustion occasion.

Whenever the air/fuel blend is correct, the aftermath of this explosion is CO2, which is the same thing people and animals breathe out.

If there is too much fuel, some molecules of HC only get one molecule of oxygen (CO) or NO molecules of oxygen, leaving the HC to leave the engine without help from anyone else.

The catalyst breaks Nox down to nitrogen and oxygen at that point and adds oxygen molecules to the CO and HC to convert them to CO2.

A byproduct of engine combustion (as a matter of course) is water vapor, which is as harmless as CO2.

The converter uses precious metals to set off chemical reactions that change the toxic gases into safer substances without changing the actual converter. That’s what a “catalyst” does.

The catalytic converter can be found underneath your car in the exhaust framework. Each vehicle will have a different location.

However, it can always be found somewhere between the exhaust manifold and the suppressor. The original is welded into place at the factory, while replacements are clamped on.

Average Lifespan Of Catalytic Converters

Catalytic converters have an average lifespan of up to 200,000 miles. Catalytic converters that were recently manufactured are worth more than those that were previously used because they can last much longer.

Even pre-owned ones, however, are ideal for scrap because of recoverable metals. The 200,000-mile mark is the cutoff point if you want to replace your catalytic converter. After your car has reached these numbers, you can replace your converter.

A Bad Or Failing Catalytic Converter Symptoms

There are warning signs that your vehicle’s catalytic converter has failed or is failing. They include:

  • Illuminated check engine light
  • Lack of acceleration
  • Stalling
  • Hard starting that won’t start at all

Most times, the significant sign of a failed converter will be an illuminated check engine light. Where the converter becomes obstructed or confined, issues like lack of acceleration, stalling, and hard starting may happen.

Can You Drive With A Bad Catalytic Converter?

To answer the question, how about we begin with a missing converter and a failed converter are two unique things?

On the off chance that the vehicle will run alright to get you from point A to point B at that point, it’s safe to drive. However, catalytic converters don’t always fail in the same way.

Assuming the converter has failed or is missing, safety won’t be a factor. Yet, you’ll want to replace the converter as soon as you find the failure or burglary.

Also, purchase no vehicle that has had its converter taken out except if you plan to repair the exhaust to make it legal again. After all, “safe” is a relative word. You may be physically safe, yet all the same, legally unsafe.

Assuming your catalytic converter is obstructed or breaking internally to where it’s robbing your vehicle of force, it may not be really smart to continue driving.

Driving in thick, fast traffic (like a packed interstate near a large city) with a vehicle that doesn’t play out the way it should cause genuine road accidents.

And recollect, a faulty converter means increased tailpipe outflows, regardless of whether you see or smell anything from the exhaust. This isn’t environmentally agreeable.

Also, carbon monoxide (one of the three gasses the converter deals with) can kill individuals in encased spaces. The danger is greatest when there are exhaust leaks and the vehicle is idling for a drawn-out period with individuals inside.

And again, assuming the converter has mechanically failed to where it limits exhaust flow, it will cause engine performance issues.

There won’t usually be any damage to different parts of your car. A notable special case for the “no usual damage” statement above would be a converter that gets boiling (like RED hot, which can and occurs).

There have been parked vehicles that set dry grass ablaze. Keep in mind, most gas tanks on current cars are plastic, as is a portion of the fuel lines.

That fire-under-the-car situation is deadly and can burn down the entire car, also the danger to individuals in or around it along with different cars.

How To Replace Catalytic Converter?

The answer to this question is mainly subject to what state you live in. A few states don’t perform discharge testing, and in this manner are indifferent if you have a failing converter. Different states, similar to California, have stringent discharge standards for vehicles.

In states with these elevated standards, failing to replace your messed-up converter will almost certainly bring about a failed emanations inspection.

Besides, a few converters are planned in a way that a failed unit will eventually confine your vehicle’s exhaust flow, which might cause your engine to fail. Except if you absolutely can’t afford a replacement, it’s something we advise you to replace.


Assuming you’re wondering How Many Catalytic Converters Are In A Ford Mustang? You’re not alone. It’s possibly the most well-known question that individuals have about Mustangs.

The answer relies upon the year and model of your vehicle, yet there’s always over one present in all models.

There are two catalytic converters in a Ford Mustang: one in the exhaust manifold on the driver’s side and one in the exhaust manifold on the passenger side.

There are no catalytic converters beneath the car, dissimilar to many cars that were worked before 1995 or somewhere in the vicinity.

Frequently Asked Questions

Do Mustangs have catalytic converters?

By removing the prohibitive factory catalytic converters from the exhaust, your Mustang can deliver more pull and force, making such a mid-pipe ideal for race applications, for example, track and drag racing.

How are catalytic converters taken?

Some criminals bring a mechanic’s creeper. Then, at that point, all they do is slide under the vehicle, eliminate the bolts holding the converter, and take it. Cheats can eliminate the unit within a little while. Typically, catalytic converters are taken from cars and trucks in driveways, strip malls, or parking garages.

Does insurance cover taken catalytic converters?

If you have far-reaching coverage on your auto insurance strategy, catalytic converter burglary is usually covered. Complete coverage may pay to replace the taken converter and repair any damage caused by its removal.
