I did a few things to enhance the sound on my '16 Z06, and quite happy with the outcome. Installed a Borla x-pipe (eliminates the secondary unmonitored cats, no CEL), pulled the NPP exhaust fuse, which leaves the flaps open, installed an AFM disabler (eliminated the 4 cyl mode, works best on A8s).
At idle, has a nice rumble, at cruising, just an altogether pleasant sound, and put your foot into it a bit, oh yeah, the beast awakens.
