Perks of Getting a New Exhaust

Are you a bit hesitant about adding a new performance exhaust system to your ride? Well, don’t be. There are certain perks of getting a new system. Let’s go over them!

Improves the Engine's Function

For an engine to function as it should, it needs a high-quality exhaust system. You can easily add more power and torque to your ride with the right purchase. It's all about allowing your engine to breathe. An engine that's able to breathe as it should will also play a role in improving the ride's noise. For those wondering, more of the engine's power is directed toward other functions when air is able to move in and out of the engine easily.

A clogged exhaust system means the engine will have to work harder. An overworked engine won’t do your car or  driving experience any good.

Improves Overall Value

As mentioned, a new system is going to make your vehicle sound better. People notice the sound of a high-performance engine. It also enhances the total value if you ever consider selling your ride to someone else for a reasonable price.

Improves Carbon Footprint

With environmentally consciousness being a hot topic, you, too, can play a role by utilizing a reliable system. You might not know this, but the chemicals present in old exhaust systems play a massive part in negatively impacting the climate. That's why a new fuel-efficient system is recommended for taking care of the environment.

Improves Gas Cost

Another perk is the ability of a new exhaust system to help save money when you stop to get gas for your vehicle. Whether you’re going on a leisurely ride or towing something heavy, we all want to save money on gas!

How to Choose a 6.7 Powerstroke Exhaust

Going for the first 6.7 Powerstroke exhaust you see in the market doesn't guarantee a good purchase. There are certain features you need to consider to ensure a great option.

The best qualities that make a top-of-the-line Powerstroke exhaust are:

The Material

You need to know about the material such an exhaust are made of. Generally, these systems are made of two materials:

Aluminiumized Steel

These steel pipes (heavy-duty) are dipped in an aluminum-silicon alloy. They offer high resistance to corrosion. They're great for any heavy-duty, off-road work you might have in mind.

Stainless Steel

Stainless steel pipes offer impressive protection from corrosion. They’re used for rough terrain work.

The Noise

The health of your vehicle can be determined by the noise the engine makes. When it comes to an exhaust system, you can opt for a muffler or a non-muffler offering. The important thing is for the system to allow your engine to breathe properly. The better the breathing system, the better the noise produced.

The Style

This point is a bit more subjective. It all depends on how you want the system to look. The important thing is not to allow a style to outweigh a performance. It's better to go for a system that's perfect for your vehicle's engine, even if the style isn't something you like 100%.

The Price

Don’t hesitate to search around for the best price. Of course, every budget isn’t going to be the same. Generally, a high-quality system is going to cost more. However, that doesn’t mean you can’t find some affordable options.

What Do I Need to Know Before Buying an Exhaust?

As some of you might already know, there are a lot of exhausts available in the market. That's why it's essential to opt for the best exhaust meant for the 6.7 Powerstroke. We hope our review list was able to help narrow down your choices.

For those wondering about what you need to know before purchasing an exhaust, we have some tips!

Types of Exhaust

You need to be familiar with the types of exhaust available.

● The Cat-Back Exhaust System usually has a special kind of muffler. While expensive, it is considered to be one of the best. It’s meant for beginners and experts.

● The Axel-Back is visually similar to a conventional factory-fitted system. However, the functions are different. They're considered to be very efficient and produce a deep sound. They are also comparatively affordable.

● The Header-Back Exhaust Systems replace almost all of the components in your vehicle's factory-fitted system. They are easy to install.

The Material

You have to be sure about the material to opt for, depending on your driving preferences. A stainless steel system is recommended if you want high durability and resistance from corrosion and rust. However, note that they are more expensive than aluminized ones.

The Exhaust

Are you looking for a single or a double exhaust system? You should know that single exhaust kits are preferred. We say this because such an item helps produce a deeper sound. Also, take note, a double exhaust doesn’t mean you’ll get excellent performance. They’re meant more for visual appeal.

The Built

Always look at the build of your vehicle before purchasing an exhaust system. You should be aware that the system you get from your vehicle’s manufacturer is going to be different compared to the aftermarket exhaust systems.

The Law

Do make sure to go over the law concerning the exhaust system you are interested in. Many of these kits are only allowed to be used during organized competitive races. Read up on the laws of your state to see what you’ll be getting into by purchasing such a kit.


We hope you now understand how vital a competent exhaust system is for your vehicle. Your engine needs to breathe, and a high-quality system is just for that. Better airflow allows for more power and torque in your car. Always make sure to go over the construction of an exhaust system kit before you purchase one. Do consider the bend, installation process, and reliability. We hope our review list has proven useful to you. Happy driving!
