The camaro NPP doesn't work like the vette.
In the vette it's quiet until you rev it past some number of rpm's.
In the camaro, the active exhaust is loud on startup then quiets down for neighborhood driving the opens up under throttle like the vette.
At like 3k rpm with Exhaust Commander you can hear the difference when pushing the button. But it's subtle.
The biggest effect is the backfiring on deceleration.
