If you’re looking to improve your Nissan GU Patrol’s towing and hill-climbing capabilities, the best way to do so is by upgrading your stock exhaust system with an aftermarket one. Aftermarket exhaust systems are one of the most sought-after performance upgrades, simply because they’re the most affordable, yet very efficient solution. Most stock exhaust systems are made using affordable materials and techniques in order to reduce the overall factory cost of the vehicle and to make it affordable to a wider audience. That leaves plenty of room for improvement, and aftermarket exhaust system manufacturers have capitalized on that fact.
However, an aftermarket Nissan GU Patrol exhaust system can do much more than just improve your ride’s performance. A GU Patrol exhaust can improve the fuel economy, sound, look and the longevity of your engine. Depending on how much you want to spend and upgrade your exhaust system, you’ll find header-back, axle-back, and cat-back exhaust systems. The difference between these is, as you can probably guess by their names, how much of your stock exhaust system they replace. Typically, you want to replace your entire system for the best results.
So how do aftermarket exhausts accomplish all of this? Well, it’s actually quite simple – they’re designed to provide a better flow by incorporating high-grade mandrel bent tubing and larger diameter pipes. These two things alone allow the gasses that flow in and out of your system to do so in a more efficient manner, which then allows your engine to burn fuel at a more optimal air-to-fuel ratio. Depending on the type of aftermarket exhaust you get, you may experience 5-30% improvements in horsepower and torque.
The two most popular materials used for manufacturing aftermarket exhaust systems are stainless and aluminised steel. There are two types of stainless steel used, T409, and T304. T409 stainless steel is the more popular one, as it’s more affordable and made specifically for manufacturing exhausts. Stainless steel is incredibly durable, has corrosion-, vibration- and heat-resistant properties, making it ideal for off-roaders who want to get more out of their vehicle. Aluminised steel is durable and boasts the same properties, although not to the same extent as stainless steel. However, aluminised steel is more lightweight, thus improving performance and mileage by dropping from the overall weight of your Nissan.
And of course, as aforementioned, aftermarket exhaust systems can improve your Nissan’s exhaust tone and look. Aftermarket mufflers aren’t designed to quiet the system, but they can change it to a higher-pitched tone, or a deeper, more aggressive tone, depending on what you prefer. Exhaust tips come in various shapes and sizes, allowing your Nissan to stand out from the crowd by adding to its unique look.
