The code can be a number of things, could just be your mass airflow sensor, you said no leaks were found. Could be a fuel injector too. Wouldn't really know till you get in there. They will never void a warranty for a muffler delete. My car has one and everyone in the dealership knows lol, never been an issue or been discussed besides "it sounds good". Just wait for dealers to reopen and get them to fix it. I'd avoid driving it as much as possible.
