The 7.3 Powerstroke exhaust can also increase pipe diameter, which is another aspect that contributes to all those benefits we mentioned.

I’ve already mentioned the best pick for your new exhaust, but let’s take a closer look at some other options too. Even though the RPG version is my pick, there may be a different one on this list that you prefer or that you know something about.

Take a look at each of the options and what they have to offer and then decide for yourself about which one is going to be the best fit for your vehicle. (Or maybe you’ll decide you like the same one that I do.)

Exhausts for a 7.3L Powerstroke – Buyer’s Guide

Okay, so now that we’ve taken a closer look at some of the best products, it’s time to look at some more features and important considerations. I’m going to share with you some of the most important features and qualities of a good exhaust for your 7.3 Powerstroke, so that you can make a solid decision in case you’re not as keen on the ones that I’ve already mentioned.

If you don’t like them, that’s fine. Just make sure that you’re following this buying guide to make an informed decision.

How to Choose an Exhaust for a 7.3L Powerstroke

Downpipe Size

One of the first things you’ll want to look at when you’re choosing an exhaust is the downpipe size. For the most part, this is going to depend on the vehicle that you’re driving. If you have a vehicle with up to 450 horsepower, then you can generally opt for a 4” downpipe or even a slightly smaller one (smaller sizes are not common but are available in some systems).

If you are driving a vehicle that is over 450 horsepower, then you’re typically going to want to get a 5” downpipe to get the best results out of it.

Material

Aluminized steel, or at least stainless steel, are going to be the best options when it comes to choosing the material for the exhaust system. You want something that’s going to be durable and long lasting but that also isn’t going to be too heavy. On the other hand, you don’t want something that’s too light either, as this could compromise the overall integrity of the components.

Overall, these two materials are going to give you the best combination of strength and weight and will make sure the system is going to last without rusting.

Muffler Included

If you are looking to replace the entire exhaust system, then this may include the muffler. Not all exhaust systems that you purchase are going to include the muffler, so you will need to take a closer look at the system you’re considering. Make sure that you know which parts need to be swapped or replaced on your vehicle before you decide on a specific system.

Purchasing parts separately may be more expensive than choosing a system that includes everything together.

Warranty

You’ll want a product that offers a warranty because this is going to let you know that the company stands behind the product. You want to be sure that you’re getting something that is built to last and that the company expects it to last for a long time to come.

The length of the warranty that you are looking for depends on your personal preference, but at least 90 days is a normal industry standard. This will give you enough time to install the new system and use it for a little while, which ensures that it’s working properly.

How to Use an Exhaust for a 7.3L Powerstroke

The first thing that you need to do in order to use your exhaust is to make sure that you install it properly. You will generally be able to snap the new exhaust into the hangers that were a part of the old system. Be sure to check out the manufacturer’s installation instructions to find out for sure what needs to be done in order to attach it properly and keep it firmly connected.

You don’t want to find yourself with another broken exhaust because this one wasn’t installed in the way it was recommended to be.

When you’re ready to use your exhaust, you don’t really need to do anything. All you need to do is just drive your vehicle the way you normally would (or the way that you wished you could before you got the new exhaust system).

You’ll be able to get the system working the way you want and drive your vehicle while you’re off-roading without having to worry about the way the exhaust operates. This is going to give you more freedom to enjoy your vehicle and to open it up entirely.

FAQs

Before I draw this one to an end, let’s take a closer look at some of the most frequently asked questions when it comes to the exhaust for a 7.3L Powerstroke.

I want to make sure that when it’s time for you to pick one out or to start the installation process, you know what you’re getting and you’re not too tied down with questions. When it comes time to replace your exhaust, you want to know exactly what you’re looking for and that you can pick it up immediately (no more digging through hundreds of results pages).

What Size Is the Exhaust for a 7.3 Powerstroke?

If you’re looking to get the exhaust set up for your 7.3 Powerstroke, the most common size is a 4” diameter downpipe. Now, you can find some that are somewhat larger or smaller than this, with others as small as 3” and some as high as 5”. These are less common, however, and will give you a slightly different outcome depending on the specific size that you choose.

If your vehicle runs with over 450 horsepower, then it’s recommended that you opt for a larger diameter pipe, leaning toward a 5” rather than a 4”. A pipe that is 4” in diameter is typically good for any vehicle that is at 450 horsepower or less.

No matter which size you get (based on the horsepower of your vehicle), you will be able to get the benefits mentioned earlier, which include better horsepower and torque, better mileage, and a deeper sound.

What Are the Ford Powerstroke Exhaust Components?

If you are looking to purchase an exhaust for your Ford Powerstroke, it will normally come with several different components. The main aspects of this system are the exhaust manifold, catalytic converter, resonator, exhaust pipe, tailpipe, oxygen sensor, and muffler.

Keep in mind that some vehicles may have more than one exhaust manifold and/or catalytic converter. This is something to keep an eye on when you’re purchasing a new system.

Also, note that not every system that you buy will include a new muffler. If you are in need of a muffler for your system, you’ll want to take a closer look at the system you’re considering to be able to see if it is available. Some of the systems that we mentioned above do come with the muffler, while others consider this to be a separate piece.

If you do not need a muffler, then this can save you some money when switching out the system. Just ensure that your new exhaust system will fit with your old muffler.

What Is the Powerstroke Exhaust Back Pressure Sensor?

The exhaust back pressure sensor takes care of operations related to the exhaust back pressure when the weather turns cold. Located at the front of the engine, the high-pressure oil pump sits to one side while the serpentine belt is to the other.

This is a very confined space and means that it is possible for a clog to occur, especially because it is connected to the exhaust manifold by a very small tube.

If there is a problem with this sensor, you could experience lowered fuel economy as well as a reduction in the overall performance of your vehicle. This will definitely affect the way that you are able to drive and the amount of fun you’re going to have when you decide to take your vehicle off-roading as well.

What Is the Powerstroke Exhaust Back Pressure Valve?

The Powerstroke exhaust back pressure valve is a small device that helps to restrict the flow of the exhaust and to simulate a load over the engine. In doing this, it’s able to decrease how long it takes for your vehicle’s engine to get to the operating temperature.

Designed in a butterfly style, it’s attached to the turbine outlet, which is located on the turbocharger. It is operated by an actuator, which uses a sort of forward and backward piston motion to adjust the valve. From there, the regulator helps to control the overall flow of oil and then reduces the overall range of motion.

What Is a Powerstroke Exhaust Brake?

When it comes to running a Super Duty turbocharger ,you’re normally going to have an engine-exhaust brake. That’s because it’s practically become a requirement. What happens is you flip a switch which is near the center stack and this initiates the engine brake.

It will then adjust the vanes on your turbocharger – the exhaust side of it, anyway – to ensure you are getting the right engine pressure.

When you’re using this engine-exhaust brake you won’t need to exert as much force on the manual brake because it will provide you with enhanced braking power. This will help you keep your vehicle under control. It’s also especially useful for those who are using their truck to pull a trailer.

This system will help to keep everything under control when you are traveling downhill.

Verdict

Overall, getting a new exhaust system for your 7.3L Powerstroke isn’t as difficult as it may seem. In fact, it’s designed to be simple and to afford you the tools that you need to drive your vehicle more efficiently. If you’re looking to get the most out of your vehicle, you’re going to want to get the best exhaust that you can.
