The BMW M5 G90 is a marvel of performance engineering, featuring the new 4.4 V8 S68 engine that delivers an unparalleled level of power, precision, and driving excitement. While the stock exhaust system is already highly engineered for performance, there’s always room for improvement in terms of sound, power output, and overall driving experience. Tuning the exhaust system of the M5 G90 with the S68 engine is a fantastic way to unlock more of its true potential.
In this guide, we’ll walk through the process of tuning the exhaust for the new BMW M5 G90. Whether you want to improve the sound of the exhaust, increase power, or fine-tune your car’s overall performance, these steps will provide you with a solid understanding of how to approach the task.
1. Understand the Basics of Exhaust Tuning
Before diving into the specifics of tuning, it’s important to understand the key elements of exhaust tuning:
- Sound: The tone, volume, and aggressiveness of the exhaust note.
- Power Gains: Exhaust tuning can help reduce back pressure and enhance engine efficiency, leading to potential power gains.
- Weight Reduction: Aftermarket exhaust solutions can reduce weight, which may improve vehicle dynamics.
2. Upgrade the Exhaust Components
Tuning the exhaust system of the M5 G90 begins with selecting the right components. The S68 engine benefits from a well-balanced exhaust setup that emphasizes both performance and sound.
Installing downpipes is one of the easiest and most effective ways to enhance the exhaust performance of your BMW M5 G90. It’s a simple yet high-impact modification that can noticeably improve both power and sound.
The downpipes play a crucial role in improving airflow from the turbocharged engine. Replacing the stock catalytic converters with high-performance downpipes can help reduce turbo lag, improve throttle response, and increase power. Downpipes also provide a more aggressive exhaust note, which enhances the driving experience.
- Catless Downpipes: These are designed to minimize restrictions and enhance the flow of exhaust gases. If you want more power and an increase in sound volume, AXI Performance M5 G90 downpipes can be an excellent choice.
- Downpipes with 200 Cells Catlytic Converters: Catted downpipes come equipped with a Hight Flow Sports Catalytic Converter, which helps to reduce the level of harmful pollutants in the exhaust gases. A sports catalytic converter is less restrictive than a factory one, allowing for improved exhaust flow and increased performance. Downpipes with sports catalytic converters are designed to strike a balance between improved performance and reducing harmful emissions. Catted downpipes help to reduce the level of pollutants in the exhaust gases. This reduction in pollutants often results in a less potent or even odourless exhaust smell.
Tuning the exhaust on your BMW M5 G90 with the 4.4 V8 S68 engine is one of the most rewarding upgrades you can make to your vehicle. By carefully selecting the right components – such as downpipes, you can drastically improve both the sound and performance of your M5.
