D22 Navara Exhaust Upgrade: Improved Performance & Sound


There’s nothing like a versatile vehicle, one you can use for multiple purposes with exceptional efficiency and ease. One with which you don’t have to worry about storage, speed, off-road or on-road conditions. The mighty Nissan Navara is a great example of a multi-purpose vehicle ready to tackle all kinds of terrain. As such, it comes as no surprise the popularity of the Navara here in Australia, especially the D22 make.

However, no vehicle is 100% perfect – not even the Nisan Navara D22. Manufacturers tend to cut costs wherever they can, and usually, that’s with the exhaust system. Many D22 owners find that the straight-out-of-the-factory exhaust simply can’t keep up with their needs and driving habits. So, eventually, they decide to make an upgrade.

If you want your Navara D22 to be 100% efficient, clean and safe, you need a quality exhaust system. Therefore, this article will focus on the aftermarket D22 Navara exhaust, as aftermarket options allow more flexibility and better quality for your ride. The goal is to teach you how the exhaust works, what to look out for, and the benefits of getting one

How Does an Exhaust System Work?

Before we get into the details of what makes a great exhaust pipe and its benefits, it’s best to explain first the parts and functions of the exhaust system. If you want to make any changes to your Navara, you must also know how it works and what you’re doing. Only then can you buy the right D22 Navara exhaust. Accordingly, we will briefly explain how it works.

The First Step

First of all, the exhaust system is not just one piece that does everything. It’s composed of multiple parts, each one doing something. The first part is the manifold, which connects to the engine and has a pipe for each cylinder. This manifold collects all of the exhaust gases and pushes them through the piping.

Reduction of Gases

The gases then get checked by an oxygen sensor which inspects the air to fuel ratio. If you’re burning too much oxygen in the exhaust, that is, not injecting enough fuel, it will tell you. And vice-versa, if you’re injecting too much fuel. Afterwards, the gas travels through a catalytic converter, where harmful emissions like nitrogen oxide, carbon monoxide, and hydrocarbons. Furthermore, there is another oxygen sensor after this step which checks the efficiency of the converter. Also, there could be multiple catalytic converters.

Noise and Release

And if you’re wondering which parts are concerned with the noise, then it’s the resonator and the silencer. The resonator isn’t always present, but its use is to reduce irritating noises from the driving experience. The silencer’s use is to remove as much noise as possible, by absorbing it. Last, you have the tailpipe which releases the fumes.

How to Pick a Quality Aftermarket Exhaust for Your Nissan D22?

Now that we’ve gone over the parts and their functions, we can focus on what you should look for in terms of quality.

The Material

The first thing you should check is the material the system’s made of. As the engine produces a lot of heat and gases, the system needs to be resistant to any damage so that you can use it long-term. If you’re looking for a material that’s strong and durable, you should choose stainless steel. Additionally, it’s also resistant to corrosion, making it ideal for rain. With that in mind, if you can get a T409 stainless, you’re in luck. It’s the most resistant type of stainless with titanium alloy. As such, if you take care of your stainless steel system, it can even outlive your vehicle.


As previously explained, the system is composed of many linked parts. They all need to be connected well with no breaks or wrinkles between them. If you’re wondering how to notice wrinkles, don’t worry. It’s nothing technical. It’s the same as the wrinkles on a human face. It’s best if you have tubing with no wrinkles as they can fatigue the metal, and with time, can cause damage and for it to break. If you want your D22 exhaust to be perfectly smooth, you should see if it’s mandrel-bent. Mandrel bending is a method that guarantees no damage to the tubes.

Sound Options

Lastly, you can even play with the sound of your exhaust. If you want a more natural sound with better performance and fuel economy, you can get a straight pipe. However, there are several disadvantages to this. It’s not cost-efficient, so you’re going to spend more money. But, even worse, it’s much louder, and there are rampant emissions. You might like the natural sound, but the people around you most probably don’t. Meanwhile, the rampant emissions are due to no catalytic converter, so you’re damaging the environment.

The Benefits You’ll Get

Finally, there are many benefits to installing a new aftermarket Navara D22 exhaust. If you want to get a better overall experience with your Navara, it can make a huge difference in several ways.

Power and Performance

The deciding factor of a car is, of course, its power and performance. If you’re looking for a more powerful ride, then the right exhaust system can make all the difference. As it connects to the motor’s cylinders, it can affect the efficiency of the motor. The quicker the exhaust fumes leave the engine, the more the motor can breathe in. You can further boost the performance with a dump pipe, as it can make a big difference.

Sound and Looks

As already explained, your choice of an exhaust system can have a big difference in sound. The straight pipe option does come with its advantages and disadvantages. But choosing a new system with quality parts and silencer can guarantee that your engine is quiet and doesn’t damage itself. Furthermore, depending on the tailpipe’s style, you can show the world that you have a unique style.

Cost Efficiency

Ultimately, a car is an investment that requires a lot of money. Thereby, you want it to last long and for it to be cost-efficient. If you install a new exhaust on your Navara, you can cut down on fuel as the motor’s combustion will be more efficient. You’ll be saving money every day. Moreover, a new system means that you’ll need fewer repairs in the future, as they’re well-made and made to last. Simply put, it saves money, time, and nerves.
