Improving exhaust note

[V8 Animal]

Had my car 3 months and 2500 miles. Had a aggressive drive yesterday and really enjoyed chucking the car around and using the box. What I noticed is the change in the exhaust note much better more like the N/A I had before.
Tell me it's not just me noticing a change in a new AMG

Did you change your boxes?

Mine is a bit on the quiet side compared to my last one

Done nothing, the gun shot type of noise seems to have gone.
