What causes the Audi R8's engine to produce a higher pitched sound compared to other models?

I noticed that the Audi R8 has a distinctly higher pitched engine sound compared to other models. What is the reason for this and is there anything I can do to change it?

The Audi R8's engine is tuned specifically for performance, resulting in a higher pitched sound compared to other models. This is due to the engine's high revving capability which enhances its power output.

There are aftermarket exhaust systems available that can change the sound of your Audi R8's engine. However, keep in mind that altering the exhaust system may affect the car's performance and void the warranty.
