How Many Catalytic Converters are In a Ford F150?

Ford’s latest pickup truck model launched by its F-Series has gained a good reputation in the market. The Ford F150 is one of the most powerful trucks known for its robust features and star performance. 

The truck offers best-in-class towing capacity and advanced outer and internal features, its on-road performance standing out from the others. So when we talk about the catalytic converters in the machine, their construction is built at the same level.

What is a Catalytic Converter?

A catalytic converter is part of the engine exhaust system, which converts the toxic gasses produced from power generation into non-toxic ones through chemical reactions before they are emitted from the vehicle.

Does My Truck Have to Have a Catalytic Converters?

A catalytic converter plays a crucial role in getting through the smog or emission test to make your vehicle safe to drive on the streets of your state or country. Your truck will not function well without a catalytic converter, and you risk having engine trouble in the future. 

Also, in most states, your vehicle has to have a converter to be street legal. Every state and country has guidelines about emission standards according to the atmosphere and climatic conditions of the region.

Types of Catalytic Converters

There exist two types of cat converters for non-harmful gasses to be emitted into the atmosphere:

The first converts only carbon monoxide & unburnt hydrocarbons, and the second converts nitrogen oxides along with carbon monoxide and hydrocarbons.

These are known as “two-way” & “three-way” catalytic converters. Until 1981, only two-way converters were in use.

After that, due to stricter emission regulations, a three-way cat system was adopted in the market and is used today. Depending on the design of the engine system and its internal mechanics, a vehicle can have one or more catalytic converters.

Catalytic Converters in Ford F150

The Ford F-150 comes with a dual catalytic converters system, making the vehicle’s emission system more rigorous concerning pollution control standards.

The system has two converters: one at the front end and one at the vehicle’s back end.

Front End Catalytic Converter

The front-end converter works as a usual three-way converter. It converts the carbon monoxide and unburnt hydrocarbons to carbon dioxide and hydrogen gas through an oxidation reaction.

Nitrogen oxides are then transformed into nitrogen gas through a reduction reaction. It supports the set of exhaustion pipes running on the truck’s front side.

Back End Catalytic Converter

The back-end converter supports the exhaustion pipes running through the truck’s backside. The back-end cat works as a usual three-way cat converter, i.e., it converts the carbon monoxide and unburnt hydrocarbons to carbon dioxide and hydrogen gas through an oxidation reaction. Nitrogen oxides are converted to nitrogen gas through reduction reaction, same as the front end cat.

Besides converting harmful gasses into harmless ones, the Ford F150 catalytic converter also acts as a filter for tiny particles. This can disturb the functioning of the engine system and screens the emission of harmful gasses that might have escaped the front end cat and convert them into harmless ones.

When Should I Replace My Catalytic Converter?

Cats generally last around 10 years, and that’s when you should consider getting them replaced. They are designed to last a long time. But over time, different factors can start to affect the converter’s efficiency and interfere with the normal operation of the truck. If you sense a problem or think the cat isn’t working properly, it’s advisable to repair or replace it as soon as possible.

Common Reasons For Converter Replacement

  • The converter has been stolen: Cat converters are made from valuable metals and are popular among scrap dealers.
  • The engine is misfiring: This affects the engine’s performance and can lead to the truck not starting.
  • Bad odor from the exhaust: You’ll notice smells of rotten eggs or sulfur.
  • Poor engine performance: When a cat fails, it can cause the engine to stall from increased back pressure.

Is It Worth Replacing a Catalytic Converter?

Because a cat is crucial in converting harmful substances such as toxic carbon monoxide and hydrocarbons into safe compounds, they must remain functioning. It ensures your truck operates smoothly by nullifying dangerous chemicals and protects your vehicle from clogging and physical damage. A clogged cat causes the F150 engine to work more than it needs to, making it hard to shift the transmission and not allowing exhaust gas to get through the muffler. Not replacing your cat could mean trouble for your Ford in the future.

How Much Does It Cost to Replace a Ford F150 Catalytic Converter?

On average, replacing your F150 truck catalytic converter can range between $1,000 to $1400. In addition, labor costs must be considered, which can be between $100 to $300, with parts priced up to $1350.


The Ford F-150 series has been known for its rugged performance in all its current and past models (XL, STX, XLT, Lariat Sport, King Ranch, Platinum, and Limited). Their Super Duty trucks are designed for towing, hauling, and off-road driving. It’s designed to put in the work. Their on-road efficiency greatly owes to the stringent pollution control measures taken while building the vehicle. 

Both catalytic converters fitted in the truck make it better and effortless for the vehicle to get through the smog and emission tests required. Plus, they are designed with the criteria that they pass the legal barriers in almost every part of the country. So you can be free of any apprehensions about legal concerns and public health regulations when purchasing and driving the vehicle.

The vehicle’s on-road performance depends on them functioning properly and as intended. Hence, their converter quality will make a significant difference to the automobile’s overall performance.

Therefore, it is highly recommended to consider a vehicle fitted with the best-suited catalytic converters for your state or country. From an efficiency and legal standpoint, the Ford F150 pickup truck is designed for that purpose.
