BMW X5 e53 Tuning, Stance, Loud Exhaust ( PART 2 ) 

2006*

Have you done anything to it yet?

Remove the box off your exhaust and you’ll get the same sound.

@@trellw.5377 when you say box you mean the silencers or the resonate ?

if i remember correctly the 4.8is has air suspension for both front and back as standard with a button that allows it to go up and down, the others if I remember correct has air suspension only at the back but no control to make it go up and down
