I'm in CT too and have the AA downpipe on my stock tune still which would probably be a pretty solid comparison and make it pretty clear if the car is tuned or not.
I know the Wagner DP is good but I think eventually it would throw a CEL at some point unless there is a spacer (which would be easy to visually spot). So if you've driven with no CEL and don't see a spacer I'd say good chance it is tuned. Another thing you can do is check the emissions systems using a tool and see if any O2 sensors are turned off. The reason this is really important is because in CT you will not pass emissions which I think is due this year or next for a 2017 car, if the system doesn't set readiness. So in that case you definitely want to know that and if it is tuned you need to find out by whom and how to get the O2 sensor turned on for emissions purposes.
