Factors to Consider

Undeniably, the engine of 5.9 Cummins is quite impressive when it comes to delivering power-driven performance. Yet if the exhaust system is not working well, it can affect the engine’s efficiency to a greater extent.

Likewise, a stock exhaust system tends to malfunction due to the accumulation of corrosion and rust. In such a condition, you will need to replace the exhaust system of the vehicle.

There is a wide variety of exhaust systems available in the market. Owing to this, it has become a tedious task for the user to select the best one.

You must consider the requirements of exhaust along with the features of the shortlisted models for a wise selection. Below mentioned are the buying considerations that would assist you in getting the best one.

Ease of Installation

One of the most important features to look for in an exhaust system is the ease of installation. For instance, if the setup process is time-consuming and complicated, it will become quite a tedious task for the user.

Consequently, you will require professional assistance for installing the exhaust system into the car, which will be a costly affair.

That is why it is recommendable to opt for exhaust systems that offer a swift and straightforward fixing system. Eventually, it would make the DIY installation easier and hassle-less for the user to save time and money as well.

Ideally, it takes around an hour to fix the exhaust system in the vehicle. However, read the instructions in the installation manual carefully to avoid glitches.


In particular, the exhaust system’s material and build-up define its durability and steadfastness in a continual application.

If the materials are not robust enough, it can significantly shorten the exhaust system’s life span. Since the exhaust systems provide power-packed output and produce extreme pressure and heat. Due to this, the user must go for the tough and heat-resilient exhaust system.

Hence, assess the material of the exhaust system and then decide which one will suffice your requirements. Commonly, the exhaust systems are engineered using either stainless steel or aluminized steel.

Likewise, the latter is more affordable but lacks robustness. The majority of exhausts made of aluminum steel are prone to rust and corrosion. Moreover, they are not suitable for use in off-road driving conditions and during the rainy season too.

Contrary to this, an exhaust of stainless steel would work well even on bumpy terrains for reliable off-road drivability. Along with that, such exhausts are ideal for heavy rains and the cold regions containing salted roads.

Overall, it is preferable to go for the stainless steel material as it is versatile and withstands all types of weather conditions with ease.

Choice of Sound

Precisely, the performance of a car engine hugely depends on the exhaust type that you opt for. As a result, you will get to experience the sound as per the design of the exhaust system.

However, the choices and preferences of the buyers always vary. Some relish having a cool and subtle sound, whereas some adventure enthusiasts like the car’s more aggressive and louder sound.

Preferably, go for an exhaust system that offers a desirable turbo sound soothing to the ears and not an unpleasant one.

Most importantly, check the regulations and laws for the noise level of your region and then decide accordingly.

Anti-Corrosion Finish

Some higher-end models of the exhaust system have an anti-corrosion finishing. Basically, it plays a crucial role in protecting the exhaust against rust and corrosion.

Usually, the finishes comprise either rhodium or chromium. Though such exhaust systems are slightly more expensive than those without anti-corrosive finishing, they are worth the money.

If affordability is not an issue for you, go for the exhaust systems that have corrosion-resistant finishing. Aside from delivering consistent performance in long-term use, they offer exceptional sturdiness as well.

Contrarily, if you require an exhaust for short-term application, say for a couple of years, invest in the basic ones.

Design and Fitting

Another essential feature to assess is the design of the exhaust system along with its fitting. Those models with simplistic designs are much easier to fix inside the engine and offer high-precision fitting.

Nevertheless, the design has got nothing to do with the overall performance of the exhaust.

Opting for a classy design will enhance the aesthetics of the engine’s most treasured accessory, i.e., exhaust system.

Moreover, examine the specifications of the exhaust and compare the same with your engines to get a perfect fitting.

On/Off-Road Driving

Some exhaust systems are made specifically to facilitate off-road driving. As a result, it enables the user to drive with utmost comfort, safety, and reliability on rough roads and bumpy terrains.

On the other hand, some exhaust systems support only on-road driving, such as daily commutation on regular roads. These types of exhausts do not perform well while driving on uneven surfaces.

Hence, it is vital to figure out for which purpose you need an exhaust system.

Weather Resistivity

Climatic conditions are quite uncertain. That is why; investing in an exhaust manifold that possesses weather-resistant properties would be a fruitful choice.

Though most exhaust systems are sturdy, not all of them can withstand extreme temperatures. Effective resistivity to dynamic climatic conditions is very important, especially if you live in too hot or cold regions.

Generally, the exhausts made from stainless steel can easily survive adverse weather changes.

Therefore, the user gets to experience comfortable driving throughout the year, irrespective of the season.

  • Extreme noise coming out of the engine
  • Reduction in the power of the engine and slow hasten
  • Backfiring caused by the engine
  • Scorching smell coming out from the vehicle
  • Minimalefficiency of the engine

Is the performance of the engine affected by mufflers?

An engine produces more power and becomes rapid when it reduces all the exhaust gases from its exhaust.

The engine slows down because of the backpressure created by the muffler to the exhaust flow.

On a similar note, the effectiveness of the vehicle is reduced and its performance is drastically slowed down if the muffler is broken or gets older.

In that situation, fumes start coming out from the exhaust system of the vehicle. Hence, to a certain extent, the muffler marks the performance of the engine.

What is a sound resonator?

The resonator changes its sound remarkably. Moreover, it is not indispensable that the sound resonator will diminish the sound, but it can do a lot more than mufflers.

What happens on removing the sound resonator?

The impact will be on the backpressure to remove the sound resonator and to exchange it with a pipe. Furthermore, this will lessen the efficiency of your vehicle.
