Do you want to get more power from your ride? Installing a new 4×4 exhaust system on your vehicle is one of the easiest upgrades you can make to get better power and improved fuel economy. It is a simple process which can be done with the help of a few simple tools in your driveway in about one or two hours. In other words, diesel engines and 4×4 go well together like coffee and cigarettes.
There are aftermarket exhausts on the market that can help you make your vehicle great again. For this very reason, in this article, we will take a look at some of the benefits of installing 4×4 exhausts.
Improved Power and Torque
The quicker the exhaust gases escape, the more power and torque your engine will produce. How quickly the exhaust gases escape is directly related to how much restriction there is in the factory exhaust. The larger the diameter of the exhaust, the easier the gases can spool up and the more boost it can produce. Installing a larger diameter exhaust will allow for quicker take-offs as well as for better over-taking power.
Better Fuel Economy
Factory exhaust systems are very restrictive. That is because manufacturers are more focused on making whisper-quiet vehicles that suit new vehicle buyers. That means, they clog the exhaust to make it quiet, but it also usually causes the engine to end up working harder to get rid of the exhaust gases. Aftermarket 4×4 exhausts free up the engine and prevent it from clogging, which, in turn, improves fuel economy.
One of the main causes of over-heating exhausts is excessive exhaust gas temperatures. When the exhaust is relatively restrictive (as almost all factory exhausts are), it’s difficult to get those hot exhaust gases away from the engine. A larger diameter exhaust is designed with mandrel bends that allow the exhaust gases to flow out of the system a lot quicker. Keep in mind that mandrel bends are a sign of a quality exhaust that has been designed well. Mandrel bends refer to an exhaust that has had its curves bent in a special way that prevents the exhaust pipe from crushing in as its bent. In other words, there’s no change in the internal diameter of the exhaust pipe, which otherwise could create unnecessary restriction and impact the vehicle’s power and fuel economy.
