It sounds completely stock under normal driving. Unless you're on sport/sport plus & changing gears around 4-5500rpms it's when you hear it sound different. Cold starts are louder too. You still have the exhaust flap too which silences it. it opens up with higher rpms.
I don't think the sound changed much since.
