What is the purpose of the Audi R8's Sport exhaust system?

I've been looking into purchasing an Audi R8 and I noticed that it comes with a Sport exhaust system. What does this feature do and is it worth the extra cost?

The Sport exhaust system on the Audi R8 is designed to improve the car's exhaust note and overall performance. It does this by allowing for more efficient airflow through the exhaust system, resulting in a more powerful and smooth engine sound. While it does come with an additional cost, many owners find it worth the investment for the improved driving experience.

The Sport exhaust system on the Audi R8 also allows for more customization options. With a push of a button, you can switch between a more quiet and refined sound or a more aggressive and sporty sound. Not only is it functional, but it also adds an extra level of personalization to your driving experience.
