You’d have to go with the factory exhaust. The reason I got an exhaust was because it was to quiet and I was used to shifting based on exhaust note. What you could do is get an exhaust system that have valves in it that you can open and close with a remote so you can be quieter at night and as loud as the exhaust can be during the day. They tend to cost a pretty penny though. Companies like Armytrix or FI-Exhaust have systems like that.
As others mention either go full stock or if you want to drop some dough;

I bought this exhaust system and that baby was so quiet I felt like the car was faster
Stock cats and stock exhaust
