If you’re looking for affordable ways to improve your HiLux’s performance and fuel economy before you take the next trip across the Australian outback, then you’re probably considering buying an aftermarket HiLux exhaust system. Aftermarket exhaust systems remove most of the restrictions that are in place from stock exhaust systems, which isn’t exclusive to the HiLux only, but most vehicles around the world. After all, vehicle manufacturers don’t have the special interest of off-roaders in mind when designing vehicles, but the more general public. So how exactly do aftermarket exhaust systems accomplish that?

Better Material Quality

Stock exhaust systems are manufactured using low-quality materials, like mild steel, in order to make the end price of the vehicle more affordable. Aftermarket exhausts, on the other hand, are typically made using higher-grade steel like aluminised or T409 stainless steel. These materials are incredibly durable, perform better when placed under extreme heat, and they’re rust and corrosion resistant.

Wider Diameter Pipes

An aftermarket HiLux exhaust will have wider diameter pipes than its stock counterpart. As a result, there’s more room for the gases to go in and out of the exhaust system. In other words, you get more clean air into the engine, which allows for improved combustion and fuel burning rates, while at the same time, the emissions that come as a result of the combustion, are quicker to leave the system.

Special Bend Technology

Aftermarket exhaust systems are made using special bending technology known as ‘mandrel bending’. This technology ensures a smooth gas flow throughout the entire exhaust system, something that stock exhaust systems don’t have.

Besides performance, aftermarket exhaust systems can improve how your vehicle looks and sounds. Most stock exhaust manifolds are made to reduce the vehicle’s noise, as most people want to enjoy a silent drive. Aftermarket manifolds, on the other hand, can provide your vehicle with a deeper and more aggressive sound, which most gearheads enjoy. Additionally, aftermarket exhaust systems made of aluminised and stainless steel may feature Chromoly exhaust tips, which look amazing if kept in proper shape. You can also decide between single and dual exhausts, giving you even more options as far as looks go when selecting the right aftermarket exhaust for your HiLux.
