Best Exhaust for 7.3 Powerstroke – Our Top Choices Reviewed

You can improve performance and efficiency with the best exhaust for 7.3 Powerstroke trucks. We review the top 4 options.

While you spend a lot of time caring for your Ford truck, it’s unlikely that you regularly think about the exhaust. However, with a simple exhaust upgrade, you can enjoy more efficiency and better performance. So, how do you find the best exhaust for 7.3 Powerstroke trucks? It might not be as complicated as you would think.

Best Exhaust for 7.3 Powerstroke

There are a lot of companies offering 7.3 Powerstroke exhaust systems, but they aren’t all created equally. That’s why you need a professional to guide you through all of the junk. We found several top exhaust models that are worthy of being installed on your Ford diesel truck. In our comprehensive guide, we look at these models and help you understand the exhaust system better.

What is a 7.3 Powerstroke Exhaust?

Your Ford exhaust system is meant to remove gases that come from the engine and send them into the atmosphere. Inside the engine, various gases are being produced. These gases include carbon dioxide, carbon monoxide and nitrogen oxide, all of which can be harmful and should be avoided.

When you install a high-performance exhaust to your 7.3 Powerstroke engine, you guarantee that these gases get where they belong. Plus, a high-quality exhaust keeps your truck motor running the way it is meant to be.

Understanding the 7.3 Powerstroke Exhaust System

The Powerstroke exhaust system contains a few different parts that work together in harmony. Here are some of the major parts you want to understand.

Ford Exhaust Manifolds/Headers

When combustion happens in the engine, exhaust gas gets pushed out of the cylinders with the help of the pistons. These gases travel into the exhaust manifold, which is a vital component bolted to the engine head. You will notice a pipe attaches securely to each cylinder, meant to collect gases and push it to the exit pipe or collector.

The stock manifold is often made with cast iron, which is inefficient. Instead, you want to swap this part for a high-performance model to gain better efficiency.

Ford Catalytic Converters

Inside the catalytic converter, the dangerous materials from the exhaust get turned into something safer. Palladium mixes together with the pollutants and starts a chemical reaction. What happens is the gases get turned into better byproducts, such as water vapor, nitrogen and oxygen, before these gases mix with the atmosphere.

When the air/fuel ratio is off in the engine, the catalytic converter can go bad. If that happens, you are going to have a much larger repair bill because this is an expensive component.

Ford Mufflers

If there wasn’t a muffler on your Ford truck, you would hear an annoying exhaust sound, unlike the aggressive tone you are looking for. The muffler reduces the sound, making it less deafening.

Most mufflers contain a resonating chamber that contains baffles to reduce the sound waves. Performance mufflers have resonating chambers that also amplify and tune the note, so you get a deeper tone. Mufflers come in a variety of inlet/outlet configurations, ensuring you get the style you want.

Ford Exhaust Tips

At the end of the muffler, you will find exhaust tips. This is the furthest part from the engine, but the diameter of the tips and the bend will still have an effect on performance. If you go with a wide diameter, more exhaust gas can flow, relieving backup. You might decide to end the Ford exhaust at the muffler, but this doesn’t have a great appearance. Instead, install a simple exhaust tip that will turn heads.

Choosing a New Exhaust for 7.3 Powerstroke

When you are ready to buy a new exhaust for your Ford truck, you want to consider the options based on these factors.

Powerstroke exhaust systems


If you need a Ford SuperDuty exhaust for your 7.3 Powerstroke, you won’t automatically look at 6.0 Powerstroke exhausts. These are different models, so you aren’t going to get the right fit. Instead, look for an exhaust based on the model year and truck that you own.


The exhaust needs to be efficient to ensure pollutants don’t get into the air. Aftermarket exhaust systems clean out the impurities better before they reach the atmosphere, reducing the carbon footprint.


The Ford Powerstroke exhaust can come in a variety of styles. If you choose a cat-back exhaust system, you get all of the parts from the catalytic converter back. When you search out a Super Duty truck exhaust, these are going to be the most popular choice. With this option, you can upgrade the diameter of the pipe to create streamlined gas flow, which increases the horsepower.

The axle-back exhaust replaces the muffler and other components after the axle. It will improve the sound quality and comes at a lower cost than the cat-back but won’t offer as much performance. Plus, it is simple to install. If you want to go all the way, you will choose a header back exhaust. This type replaces every exhaust system component coming off of the header moving toward the back of the truck. Obviously, this will be the most expensive option, but also offers you a big increase in performance.

Exhaust Pipe Diameter

When you use a piping system with a larger diameter, the engine can breathe easier. The gas won’t build up as much because there is less pressure. On the flip side, small pipes or an exhaust that has bends and turns traps the gas, creating back pressure, which reduces horsepower and performance.

Exhaust Material

There are many exhaust materials the parts could be made from. Mild steel exhaust parts are cost-effective. However, the stainless steel components offer more corrosion-resistance and tend to last longer.

Single vs. Dual Exhaust

The single exhaust normally sits on a smaller engine type. It contains a Y-shape that traps the gases at the manifold and sends it out through a single exhaust pipe. You can add a tip to these exhaust systems to create the look of a dual exhaust, but that does nothing to affect the performance. However, the single exhaust is the lowest-cost way to upgrade an exhaust. If you prefer, you can choose a dual exhaust system to expel the gases through two pipes. With a larger engine, this is the best way to handle the exhaust if you plan to boost efficiency and performance. In this configuration, there are two pipes coming from the manifold to expel the gases out of the back. Of course, the extra pipe means more installation time and a higher price tag.


Your main goal might be to save money on a new exhaust, but that’s not advised. Sure, getting a deal is always a good thing. However, it’s not good to sacrifice any amount of quality to save some change. We recommend that you pick an exhaust system created by a reputable brand for the best performance. You can read through customer reviews to get a feel for the durability and performance. Plus, a warranty adds more value to the mix.
