So you're absolutely certain there's no way the internals of the exhaust could have changed without a different part number? Is that just not something they would or could ever do or is it possible?

Anything is possible, but unlikely at this point.
Again, the differences could come down to one being broke-in and the other not along with different firmware controlling the valves and EWG's. You have to keep this in mind. A lot of variables between these two cars.
