An exhaust system consists of pipes that draw gases away from the engine to the open air. When a car is running, its engine produces gases, including Carbon Dioxide, Carbon Monoxide, and Nitrogen Oxides. These gases are harmful to humans in large quantities, especially Carbon Monoxide.

This is why the exhaust system drives these gases out before they reach the cabin. So there is no denying that good quality and working exhaust system is very important in any car. We have made a list of the best exhausts for a 6.0 Powerstroke truck.

Are All Exhausts The Same?

Exhaust systems can vary depending on a number of different, but there are basically three different types of exhaust systems, which are discussed below.

When replacing a factory installed exhaust system, you have one of three options.


This replaces everything from the catalytic converter back. They are the most used exhaust systems for different reasons, which we will discuss later.


This type only replaces the mufflers of the exhaust system from the axle back. They are mainly used when you just want to improve the sound problem of your car. They are cheaper than the cat-back exhausts and have a simpler installation.

Header Back

This system replaces all exhaust system parts and requires complete installation. They are much more expensive because they include all tailpipes and mufflers. They let you increase the diameter of the system as well for a better flow of gases.

Another way one exhaust system might differ from the other is its configuration.


These systems are used with smaller engines and are designed in a Y shape. They collect gas from the manifold and send it outside through a ‘single’ pipe. Some single exhaust systems can be bought with an extra tip to achieve the same look as a dual system.


Dual exhausts, as the name suggests, expel combustion gases through two pipes and are used with larger engines for more efficiency. They have separate pipes that take gases from each manifold first and then expel through two pipes. They are more expensive but also give more performance upgrades

What is a Cat-Back Exhaust?

Cat-back gets its name from the back of the catalytic converter. This system includes tailpipes and mufflers from the back of the converter to the exhaust tips. They are the most common types of exhaust systems and are the best at improving horsepower. When installing, you can choose a different and larger diameter to improve gas flow. But you can’t go overboard with it and have to stay in the recommended limit for your engine. For a 6.0 Powerstroke, anything from a 3.5 to 4-inch is a good option.  

What Should I Look For When Buying an Exhaust For My 6.0 Powerstroke?

When deciding to replace any engine part, you need to do research to make sure it is all compatible with your car and other components. If you are using a 6.0 Powerstroke, here are some of the things you should keep in mind.

Pollutants Emitted

The main reason for an exhaust system is to expel gases outside. In fact, it’s the only job of the exhaust system. A good and new system will be clean from impurities and reduce your carbon footprint. 


Larger diameter exhaust pipes are like giving your lungs more room to breathe. You need to minimize the pressure inside the pipes to pump the gases out. If your pipe is small and has kinks, the gases expelled will not be enough. This can lead to back pressure and reduced horsepower. So a large exhaust or a one with little restrictions will improve car performance.

Build Material

Look for exhaust systems that are made using stainless steel. The advantages are obvious, no corrosion, and better durability. Your car will face many different climates throughout the year; depending on where you live, it can be subjected to snow, rain, or extreme heat. A stainless steel construction will be able to better handle all that.

Perks of Getting a New Exhaust 

If your car already has an exhaust system in it, then why go through the trouble of investing in a new one? Well, there are many reasons you need to consider upgrading, which are explained below.

Cleaner Gases

You will notice that older cars expel a lot more black gas than newer ones and are harder to start. Some of it might be due to the engine, but the exhaust system definitely plays a role. Over the years, pollutants build up and reduce the efficiency of the system. A newer system will result in cleaner gases and give your car a better look.

More Horsepower

When changing the exhaust system, you can opt for a larger diameter pipe. As we have discussed before, larger diameter means fewer restrictions and more room for the gas to flow. This makes the engine more efficient as it does not have to work against itself to fight any back pressure from leftover gases. It improves fuel efficiency and, as a result, horsepower.

Less Noise

When choosing a new exhaust system, you can replace the muffler as well. This will automatically result in less noise output and a smoother ride.

How to Install Exhaust on 6.0 Powerstroke

Installing an exhaust is not easy, and if you don’t have a lot of experience with cars and engines, then you should hire a professional. But if you are confident in your skills, then you can follow these instructions below.

  1. You will need a muffler, clams, piping, and tip.

  2. Remove the stock exhaust by cutting 3 inches in front of the catalytic converter.

  3. Next, cut three inches behind the catalytic converter.

  4. Then cut the part where it curves near the transmission and remove the cut pipe.

  5. Cut 2 inches behind the muffler and remove the tailpipe and then the muffler.

  6. Remove the clamp that attaches the exhaust pipe to the turbo.

  7. Put the new pipe where it goes and tighten the clamp.

  8. Install the pipe that needs to connect to the catalytic converter.

  9. At the joint, install a clamp to secure in place.

  10. Then attach the converter in place and install a clamp at the joint.

  11. Next put the muffler in the muffler hanger and then put in the first section of the tailpipe with a hanger.

  12. Add the next section of tailpipe and secure joint with a clamp.

  13. Add the adapter pipe with a clamp and measure the distance between it and the muffler.

  14. Cut a straight pipe of that length leaving some extra room and add it between the adapter and muffler.

  15. Add the hanger to the pipe and a clamp at the muffler.

  16. Make sure no pipe touches the frame or spare tire.

Car exhausts are not the most complicated part of the combustion process but definitely one of the most important. They can have a direct impact on your engine’s health and performance. They also affect the environment in a big way, so choosing the right system for your car is very important. Even if you don’t care that much about your carbon footprint, choosing a cleaner and system always means more fuel efficiency, which means more mileage with less fuel spent. And that is something we all care about.
