When I was shopping I test drove 2 identical v6 auto 2LTs at different
dealers. Both had the stock exhaust, RS package, v6, and A8 auto.
Both had the same sounding exhaust notes piped into the cabin.
Both were equally awesome sounding.

When floored, you would hear a deep powerful note piped into the cabin
with a distinct ratcheting sound in the background as the rpms ramped
up. A deep roar with a distinct ticking. I was sold sold sold...

I ordered one in blue with the same specs. But after I drove the car
away, I noticed the exhaust sounds much softer/mellower with no
ratcheting/ticking sound in the background. Not nearly as loud either.
I'm disappointed with the lack of roar and ratcheting sound.

Things I ruled out:

1. I tried taking out the foam from the "sound tube" that pipes engine
noise into the passenger compartment through the firewall. That had
almost zero change to the sound. Still no ratcheting/ticking sound and
the roar is not there. Still subdued, mellow, and not as loud.

2. The "sound tube" hole through the firewall is not blocked. I shoved a
socket through it and it fell to the front driver side floor mat.

3. I ran the tank bone dry and tested with reg (87) and super (93) unleaded
gas. no change the sound

4. Tried launches with traction control off. no change.

5. Tried launches in both sport and touring mode. no change.

6. I slapped myself in the face (twice) to make doubly sure I was not
trapped in a nightmare. I seem to awake.

Can someone out there give me some suggestions?

Here is my suggestion:

Try using your rev limiter!

or buy a Borla exhaust.
