Bf 110 G-2 Engines sound

[Reckoner_]

Hello, I was flying the Bf 110 G-2 for a bit and I noticed that something wasn't quite right with the way the two engines sounds.

 

I have the impressions that the Right and Left engines sounds different. The right engines sound like the on the Bf 109 G-4, while the left engines sounds more like the one on the Bf 109 F-4.

This is something that does not happen in the Bf 110 E.

Are they supposed to sound different, is it a bug or are just my ears to not work properly?

 

I leave a small clip with the timestaps in the comment to help notice the difference in sound at the different power settings with one engine at idle.

Left engine Normal mode 1:51 

Right engine Combat mode 1:17

Left engine Combat mode 2:19
