Are All Exhausts the Same?

To put it simply, not all exhausts are the same. They differ in type, construction, configuration, and material. First of all, exhaust systems can be cat-back, axle-back, or header back. Cat-back systems usually work with a tailpipe and a muffler and use catalytic converters in the emission process.

One difference in the construction of different exhaust systems is the diameter of their pipes, which is based on your engine’s size and RPMs. Another difference between them is the pipe bends. They are either constructed using a crush bending technique or mandrel technique that prevents the pipe walls from collapsing.

Secondly, exhaust systems may be a single, dual exit, dual crossover, or dual based on their configuration setups. A single setup is based on a single exhaust setup, i.e., muffler having exhaust point, which makes it cheaper and lighter in weight. Dual exits work on a similar configuration as a single setup, but their mufflers have two exhaust points instead of one. 

Dual crossover systems have two separate exit pipes along with two muffler exhaust pipes. They also have a crossover pipe that allows gases to freely exit between two other sets of pipes that balance out the pressure on both ends.

Thirdly, the materials used to make exhaust pipes may either be mild steel or stainless steel. Mild steel is an inexpensive option, yet it cannot resist corrosion. On the other hand, systems made up of stainless steel are a bang for your buck because they do not corrode in rainy or snowy weather.

How to Choose a 7.3 Power Stroke Exhaust System

Several variants of the exhaust system in the market may confuse you while choosing the best one for your 7.3 Powerstroke engine. For that reason, we have specified some of the main features you need to consider before making a purchase:

Four-Inch Pipe 

You will need an exhaust system whose pipe has a minimum diameter of four inches so it can freely allow toxic gases to exit. A five-inch pipe can help perform minutely better. However, a pipe with a size that is less or more than this range cannot perform the job well.

Stainless Steel

Make sure to choose an exhaust system that has been built with fine quality material and stainless steel, so that corrosion can be prevented when the weather gets humid or rainy.


Try to go for a system whose setup minimizes back pressure on the pipes, so the reduction in horsepower can be avoided.

What Recent Buyers Report

Buyers were quite happy with the easy installation of this product and they loved the sound the engine produced after that. A few of them found it difficult to fit in their engine and some complained about bent pipes. However, the majority of customers found the price to be pretty reasonable, making this a sound investment.

Why it Stands Out to Us

This product is best suited for vehicles with a 7.3 Powerstroke engine since it has the perfectly-sized pipe for that. It seems like a complete package with fine quality steel, a two-year warranty, and enhanced performance. Since the product doesn’t rely on any muffler, the power of the engine is increased several times.

Who Will Use This Most

This product can be used by people who love to experiment with their cars, as it functions as an add-on or modification for their factory engine. It is also a treat for individual truck drivers and other vehicle owners who are looking for a better driving experience while achieving cost-effectiveness.

To prevent your engine from deteriorating over time, it is essential to expel harmful gases with the help of exhaust systems. This exhaust system not only upgrades your engine’s performance but also helps you save up bucks by increasing your fuel efficiency.

Advantages of Investing in a Quality Exhaust

Exhaust systems eliminate harmful gases from your engine which allows your engine to breathe better and produce more power for your vehicle. Some of the main benefits they provide are listed down so you can be well-informed about their usefulness. 

Improves Engine Performance

Harmful and unnecessary gases produced during the combustion process may deteriorate an engine over time. They need to be eliminated by using exhaust systems. If the diameter of the exhaust’s pipe fits perfectly with your engine, then it can help exhaust harmful and toxic gases efficiently. This not only increases torque but adds to the power of your engine.

Improves Fuel Economy

With increased power of the engine, less fuel is consumed to move a vehicle forward. This helps reduce fuel costs by a considerate amount. Hence, exhaust systems can make your driving experience efficient and more economical.

Reduced Greenhouse Gases Emission

Cat-back systems convert toxic carbon monoxide to less dangerous carbon dioxide before releasing it out. Hence, the harm caused to the environment is significantly reduced by using exhaust systems.

Aspects to Consider Before Buying

The main features that need to be considered while choosing the best exhaust system are usually subjective and depend on the different requirements of the buyer. However, some key factors should be considered before making a purchase.

Cat-Back or Axle-Back Systems

Exhaust systems should be cat-back since they help fulfill the legal requirements of emissions of exhaust gases. Depending on the design of catalytic converters, they can allow the free exit of gases that increases engine efficiency. However, axle-back systems can be a good choice if you are looking for inexpensive and easy-to-install exhausts.


If you want to reduce sound levels, you should prefer silent muffler designs. Alternatively, if you like your truck to roar, you can choose a muffler to increase the bass of your engine.

Heavy-Duty Material

Poor quality can result in rapid corrosion in unfavorable weather conditions. Hence, make sure the material used in these exhaust systems is stainless, heavy-duty steel to prevent corrosion.

Pipe Diameter and Pipe bends

Choose a pipe diameter based on your engine RPMs and size. For pipe bends, you should prefer the stock exhaust pipe manufactured by the mandrel bending to prevent pipe walls from collapsing.


The above-mentioned exhaust systems may vary based on their material, configuration, and construction, but they all serve the same purpose of pumping up your engine to higher standards of performance and efficiency. The article has narrowed down the best options, along with their features so you can make an informed decision before making a purchase.
