Why does my Audi R8 make a loud noise when accelerating?

I recently purchased a used Audi R8 and have noticed that it makes a loud noise when I accelerate. It sounds like a high pitched whine or whirring noise. Any idea what could be causing this?

It's possible that your Audi R8 is equipped with a sports exhaust, which can create a louder noise when accelerating. You may want to check if the previous owner made any modifications to the exhaust system.
