Where are the loud pops?

Recently had the chance to drive the m340i at the mtown your, but when I drove it in sport, I couldn't get the car to make pops (accelerate up to 5krpm and let off). My 340i has a res delete, so I can hear them on my car, but I thought the m340i has a no res exhaust from factory. did they program them out?

Did you drive it in sport plus? The pops are very subtle in sport, much more aggressive in sport+. I get the occasional "gunshot" style bang mixed in with the pops and crackles.

Car sounds just fine. Try driving it in Sport+ or go purchase some resonated exhaust tips and throw them on a 2001 Acura RSX

My car in Sport+ sounds very aggressive with pops and burbles. In Sport, certainly a little less loud, and in Comfort or Eco, pretty much no pops or burbles.

So is there an actual difference in exhaust sounds between sport and sport plus?

Like OP, I have a 340i with a resonator delete and the "gunshots" are awesome but I never heard any difference between sport and sport plus on a F30.

Yes there is a big difference in exhaust note after let off. I test drove the car today about 30 minutes and man!!! The shifts are quick, handling is very responsive. Threw the car into sport + with paddle shifter mode, and my CA said "don't baby her". Hit about 7k rpms and let off and the pops will make you smile. Picking up my car on Saturday
