BMW M4 with AKRAPOVIC Titanium Exhaust sounds good !

N55 with exhaust still sounds better, but this is an improvement for sure.

I absolutely love the new M3/4 but this sound... not that great (in my opinion)

not bad but not impressive 

People complaining about the sound probably have $10 speakers LOL 

Etwas besser aber immer noch Scheiße HAHAH

Der m4 von jp-Performance hat nen besseren Sound checkt mal deren Account aus

It's always sounds like a pussy car. Not even better than an AMG stock car...

M3 :( i missed u ...

I dont understand why people are being so hard on the new M4! Yes it doesnt sound as good as its predecessors, but still sounds exciting once youre used to it! And as a whole package, the 4 door M3 is not only the best BMW to date, but the best car in the World! 

E46 still king

"good" is a bit of an overstatement if you ask me.
"better than stock" is more like it.

Sounds better than that factory crap, but still sounds like poo to me lol.
