Default Advice please !

After 6 years of not owning a Vette, I purchased a 5600 mile 2015 Z51 three days ago and have much to learn. My last Vette was a 2011 Grand Sport with the performance exhaust. I discovered on this forum which fuse to pull to open the exhaust full time on that car. Can I do the same with this 2015?? If so, which fuse do I pull? Thanks !

Fuse 42. Just understand that if you go into 4 cylinder mode it will sound like crap.

Auto can go into 4 cyl in all drive modes, manual only in Eco mode. There is the Range device to prevent auto from going into 4 cyl mode.

Just so I understand, if you have a manual, and pull #42 fuse the exhaust will be open, and not go into cylinder mode?

With manual, you would need to tell t to go into V4 mode.
If you have an A8 you need a tune or a range device or to have it in manual mode to prevent going into V4 mode.
Pulling the fuse, if you have NPP, keeps the NPP valves open so your exhaust is in loud mode all the time.

Pulling the fuse has nothing to do with V4 mode. It only keeps your exhaust open.
