NPP

So. Admit an old topic but I want to make sure I don’t f nothing up 😂

Have a 2018 SS with borla which sounds mint.

Just picked up a 2021 zl1 with NPP but want to get used to the car before I decide what to do to it but it does need to sound as good as it can. What can I do? Set it to tour ? Should I pull the fuse for the valves? I want it loud and don’t care about neighbors but don’t want to f up the car with back pressure or anything?

Advice while I get used to the car and decide what I want to do to it my friends? Thanks.
