Well, considering that they are two completely different motors, they will sound different from one another. One being an M50B20, and the other being an M52B28;That being said, the intake should sound differently if you remove the airbox, regardless of engine size since the airbox muffles the sound of the air intake. It doesn't make sense to me for the carbonio intake would sound the same as a stock airbox.
BMW...Now you're playing with power.
