REAL in-cockpit sound recording from a MESSERSCHMITT Bf-109G2.

[Sternjaeger II]

Defo a great soundtrack,kinda made me feel like the Dude from Big Lebowski when he's listening to bowling matches on his Walkman lol

The sound would probably be very similar to the Emil,but there are many things that affect the noise of a plane (apart for the most obvious ones,there's stuff like aerodynamic noise,propeller noise,structural resonance etc..). Fortunately there are airworthy Emils,so I don't think it would be hard to get hold of their recordings
