Cat Delete [Meaning, Advantages, & Disadvantages]

Catalytic converters have been standard in vehicles since 1975. They help reduce emissions, but they can also negatively impact your vehicle’s performance.

There are pros and cons if you consider deleting your catalytic converter (CAT delete).

In this post, we’ll look at the benefits and drawbacks of a Cat delete and what you can expect to pay.

Cat Delete

What is a Cat Delete?

A cat delete refers to removing the catalytic converter from a vehicle’s exhaust system. It is done for various reasons, including improved performance, increased exhaust sound, and weight reduction.

However, it is important to note that the legality of cat deletes varies by location, and removing the catalytic converter can potentially increase emissions and reduce fuel efficiency.

Catalytic converters are important emission control devices that help reduce harmful pollutants from a vehicle’s exhaust.

However, some car owners remove them for improved performance, increased exhaust sound, and weight reduction.

The process of removing the catalytic converter is called a cat delete. Removing the converter reduces the exhaust system’s backpressure, which can result in improved horsepower and torque.

Removing the catalytic converter can also increase emissions, harming the environment and violating emissions laws.

The engine may also have to work harder to expel exhaust gases without the catalytic converter, which can result in reduced fuel efficiency.

Choosing the right product for your vehicle is important if you consider a cat delete. Make sure the cat delete kit is compatible with your vehicle’s make, model, and year.

Also, choose a high-quality product built to last and will not harm your vehicle’s performance. Consider the cost of the kit and weigh the potential benefits against the price.

Advantages of Cat Delete

1. Enhanced Engine Sound

The most prominent benefit of a CAT delete is the improved engine sound. The engine’s sound becomes more pronounced and aggressive, particularly in big engines such as a V8. This can be a cost-effective way of enhancing the sound of your car.

2. Power Boost

The restriction in the flow of exhaust gases caused by the catalytic converter can lead to small power gains upon deleting it.

The back pressure is reduced, allowing the engine to work more efficiently, resulting in a slight increase in power. The power boost can range from 15 to 30 horsepower, depending on the engine and tuning.

3. Weight Reduction

The catalytic converters are relatively heavy, and deleting them can result in a weight reduction that can improve fuel economy and performance.

The weight savings can add up if multiple catalytic converters are deleted.

4. Low Cost

A CAT delete is an affordable performance modification, with costs ranging from $50 for a DIY job to a reasonable amount for professional installation.

The process is simple and doesn’t require any special skills or knowledge.

Disadvantages of a Cat Delete

1. Air Pollution

Catalytic converters reduce pollutants and emissions, so deleting them will result in more air pollution.

This includes increased harmful pollutants such as carbon monoxide and NOx, which contribute to acid rain, smog, and health problems.

2. It’s Illegal

Deleting a catalytic converter is illegal in most states in the US and many other countries. This can result in a fine for driving without one and may cause an exhaust emission inspection failure.

3. Decreased Gas Mileage

Catalytic converters can improve gas mileage by reducing pollutants in the exhaust. Deleting them will likely not result in a noticeable change in gas mileage.

4. Decreased Resale Value

Deleting the catalytic converter can decrease the resale value of a car, as most people prefer legal cars that won’t cause trouble.

5. Void Warranty

Deleting the catalytic converter will void the warranty on the cat and the exhaust system. Any issues with the car after deletion won’t be covered under warranty.

6. Engine Tuning Required

Deleting the catalytic converter requires engine tuning as it helps maintain backpressure in the exhaust system.

Without it, the engine won’t run as efficiently and may cause a decrease in performance and trigger a check engine light.

DIY for Cat Delete

The DIY process for a CAT Delete can be challenging, as it requires specialized tools and a certain level of mechanical knowledge.

It’s important to read and follow the instructions carefully, and if you’re not comfortable with the process, consider hiring a professional mechanic.

Research your state’s regulations and laws, and ensure you have the proper tools and equipment. You’ll need a jack and jack stands, a socket set, a wrench set, and a cutting tool (such as a hacksaw or bolt cutter).

Here is a general step-by-step guide for a DIY CAT Delete:

  • Locate the catalytic converter in your car’s exhaust system, typically located in the center of the undercarriage.
  • If your car has a heat shield, remove it using a socket and ratchet.
  • Using a socket and ratchet, loosen the bolts that hold the catalytic converter to the exhaust system.
  • Once the bolts are loosened, remove the catalytic converter from the exhaust system.
  • Install the new pipe in place of the catalytic converter, ensuring it’s securely bolted.
  • Start the engine and make sure it runs smoothly. If you notice any issues, shut off the engine immediately and troubleshoot the problem.
  • If your car’s check engine light comes on after the CAT Delete, you may need to retune the engine.

Why Catalytic Converters are Vital for the Environment

Catalytic converters play a crucial role in reducing toxic emissions from car exhaust.

They transform harmful pollutants into less hazardous substances through a chemical reaction facilitated by a catalyst, typically composed of precious metals like platinum or palladium.

The catalytic converter breaks down and transforms toxic emissions into less harmful gases before they are released into the atmosphere.

This helps to mitigate short-term and long-term health impacts, such as asthma, heart disease, cancer, and premature death.

Removing a catalytic converter, also known as a “cat delete”, has severe environmental consequences.

It increases the number of pollutants released into the air, as well as reduces fuel efficiency, which in turn increases the vehicle’s emissions.

Catalytic converters were first introduced in the 1970s to reduce car pollution. Today, they are a legal requirement in most countries and states.

FAQs on Cat Delete

Does Cat Delete Make Car Louder?

Yes, a cat delete can make a car louder. The catalytic converter muffles the exhaust sound, so deleting it can result in a noticeable increase in volume.

However, the extent to which a cat delete will make a car louder will vary depending on the vehicle and the type of exhaust system it has.

How Much HP Does Cat Delete Add?

The actual horsepower gain from a catalytic converter delete can vary depending on the make and model of the vehicle, as well as other modifications that have been made to the engine and exhaust system.

On average, a catalytic converter delete can increase horsepower by 5-15%.

However, this improvement in horsepower may come at the cost of decreased fuel efficiency and increased emissions.

Can Cat Delete Damage Your Car?

Yes, a catalytic converter (CAT) delete can potentially damage your car if not done properly. The catalytic converter helps regulate the emission levels and backpressure in the exhaust system.

If it is removed without adjusting the engine’s tuning, it can cause the engine to run inefficiently and potentially lead to damage over time.

Additionally, if the CAT delete is not installed properly, it can lead to leaks and other issues in the exhaust system.

CAT delete can increase your vehicle’s performance, but it’s illegal in most states and can harm the environment.

Additionally, it can void your warranty, decrease the resale value of your car, and require tuning. If you decide to delete your catalytic converter, do so legally and with caution.

While a Cat delete can give you the performance boost you’re looking for, it’s important to consider the consequences before making a decision.

Whether you’re an avid car enthusiast or want a more powerful ride, it’s important to weigh the pros and cons of a Cat delete before investing your time and money.
