Which made me think the pops were fake noise and not real.
They are real. Have someone rev ur car and stand near the exhausts.

Obviously a lot of it is amplified thru the enhanced sound inside, but there is pops and burbles even in the 330i in sport mode, just nowhere near what the m340i sounds like.
