Why does the BMW M3's engine sound different from other cars?

I recently test drove a friend's BMW M3 and noticed that the engine sounded different from other cars I've driven. Can you explain why that is?

The BMW M3 is known for its signature engine sound, often described as a 'growl'. This is due to the engine's straight-six configuration and BMW's use of a unique exhaust system. The design of the exhaust allows for air to escape in a controlled manner, creating that distinctive sound.
