Have you noticed a drop in the car’s performance recently? The exhaust system can be the source of this problem. On that subject, you should think about getting a cat-back exhaust.

When it comes to improving the car’s efficiency, there are unlimited options. Whenever it comes to the exhaust, this is undoubtedly true. If you’re looking for exhaust modifications, you may have heard of the phrase Cat back exhaust.

What Is a Catback Exhaust?

A cat-back exhaust improves airflow by modifying everything on the exhaust from the catalytic converter (the namesake of the catback exhaust). A pipe connects the silencer to the exhaust system, and the exhaust point completes the cat-back network. Other variations, like mid-pipe, or Y pipe, are included by some producers.

Cat-back exhaust improvements are an easy approach to increase the power of your car. To alleviate back pressure, these renovations usually entail adding bigger plumbing with fewer abrupt or sudden curves. Turbulence is a force that opposes the passage of exhaust gases. The greater back pressure you can eliminate, the more effective the unit will be, and the horsepower will improve as a result.

In most cases, a cat-back pipe improvement may be changed out for the standard pipe without any changes. Cat-back systems come with all of the components you’ll need to upgrade your old exhaust. The only expenses you’ll have to consider are the equipment and setup.

If you are looking for a cat-back exhaust for your vehicle, I would definitely recommend doing a quick search here!

What Are the Benefits of a Catback Exhaust?

1. Horsepower Enhancement

An exhaust pipe that loses 10-20% of its power can be the stumbling block between the vehicle and its maximum potential. The cat-back exhaust pipe adds a significant increase to the car’s power and torque output.

The cat-back design has a bigger width than a typical muffler; the huge hole allows more air to flow freely. The cat-back tubing is composed of a high-grade core to ensure smooth air circulation.

2. Improved Fuel Economy

Another major benefit that a vehicle gains after installing a cat-back device is improved fuel economy. Because the cat-back design enhances circulation, the motor doesn’t have to push as hard to remove exhaust gases.

The lower resistance reduces the stress on the motor, resulting in lower fuel usage. However, on highways and local roads, vehicle MPG or gas mileage increases.

3. Spectacular Sound

A Catback exhaust aids in the enhancement of a vehicle’s sound. It is an exhaust design that will exactly fit your lifestyle, based on your preferences. When looking for a cat-back setup, make sure the sound meets your taste.

Because a cat-back exhaust really is anything past the catalytic converter, you have a ton of options to choose from, from exhausts that crackle, to exhausts that open and close to make it louder or quieter at your will.

4. More Strength

A free-flowing cat-back muffler is usually made of larger size pipe and higher-grade steel than the original exhaust. Decreased back stress at the exhaust pipe as a result of these adjustments allows the motor to breathe better and produce more energy and torque.

The layout of the exhaust pipe, the diameter piping utilized, the kind of curves, changes, and muffler style all have a role in horsepower improvements.

This means that if you have an exhaust that is currently rusting out this new exhaust will not only be better for your car, but will likely last considerably longer on your vehicle.

What Are the Downsides of a Catback Exhaust?

The maintenance of an exhaust system can vary from simple to complex, based on the automobile. If the car is on the very complex end of the spectrum, expect a lot of bespoke bends, which requires a lot of labor time at the muffler shop.

The part of the muffler that goes from the converter output to the exhaust ends is known as the cat back. Exhaust designs with this function often have a big tube for decreased back pressure.

A cat-back exhaust has bigger pipes, which allows your car to move better. However, it may lead to a productivity drop as gases build up and leave the system more slowly, resulting in speed, rpm, and power loss.

When there are too many curves and the pipes must travel a roundabout route (for example, if you wish to move from single to customized dual exhaust), you may find a system that is just like the OEM, with minimal performance advantage. It’s especially true on old vehicles where the exhaust must be channeled around a petrol tank.

If your car is still covered by the manufacturer’s warranty, it’s important to verify if exhaust modifications may cancel it. Some people believe these machines are too loud, and they are appropriate in some circumstances. The equipment can be expensive. If the automobile is vintage or rare, a Catback exhaust can depreciate its value.

Frequently Asked Questions

Is a cat back exhaust a straight pipe?

A cat back exhaust and a straight pipe are not the same thing unfortunately. Straight piping a vehicle generally requires removing the catalytic converter, and a cat back exhaust by definition leaves the catalytic converter in place, and replaces everything behind that point.

Is Catback exhaust legal?

A catback exhaust does not remove a catalytic converter, which is the main reason why an exhaust may not be legal. However this doesn’t account for things like the exhaust being too loud, which can also be the reason an exhaust may be illegal. Make sure to refer to your local laws.

What’s the difference between Catback and regular exhaust?

A catback exhaust is what replaces a regular(factory) exhaust, however you realistically could get a catback that sounds and acts just a like a normal exhaust, or can be completely different.


A catback exhaust is an awesome option for people that want to bump the horsepower of their vehicle, and/or completely change the sound of it! These exhausts tend to keep vehicles legal in most all states, making them something anyone should be able to do on their vehicle with little research or risk.
