The Navara D22 is one of the most popular pickup trucks in Australia. It’s reliable, tough and comfortable, making it one of the best off-roading vehicles on the market. However, as is the case with almost every other pickup truck in the world, the Nissan has left a ton of room for improvement in the exhaust department. An aftermarket Nissan Navara D22 exhaust system can be one of the best upgrades you get for your Navara. It’s a cost-effective way to improve performance, mileage, sound and looks. However, not all aftermarket exhaust systems are the same. That being said, here are a couple of important factors you’ll have to consider when shopping for a brand new aftermarket exhaust system.
There are many different brands that manufacture quality Nissan Navara D22 exhaust systems. Some of those exhaust systems are universal, while others are made for a specific vehicle model, make and year. Preferably, you want one that’s made to fit your specific Navara model, make and year, just because those are easier to install and require little to no extra modification. Some of the better aftermarket exhaust system manufacturers are MagnaFlow, Outback Exhausts, Factory Direct 4×4 Exhausts and Flowmaster.
The materials the exhaust system is made of can make a huge difference, and different materials perform differently depending on external factors like humidity, heat, etc. The most popular materials aftermarket exhaust systems are manufactured from include stainless steel and aluminium. These materials are durable, corrosion-resistant and vibration resistant. Stainless steel is the more durable solution, but they’re also more expensive. Aluminium, on the other hand, is more affordable and more lightweight.
Exhaust systems come in three basic types: header-back, cat-back and axle-back. The difference between these types is how much they replace from your stock system. Header-back exhaust systems replace the entire stock system and thus offer the most benefits. Cat-back exhausts replace everything from the catalytic converter backwards, and they offer the best value, and axle-back exhaust systems replace the muffler and exhaust tips, so they only offer benefits in terms of look and sound.
As briefly aforementioned, aftermarket systems that are made for your specific model, make and year Navara are easier to install than universal aftermarket systems. Header-back exhaust systems are relatively easy to install if you’re handy with tools, but I’d highly recommend you let a professional do it regardless just to be safe. That being said, the installation cost should also be factored in with the price of the aftermarket system.
