This comment is fairly old, but you can absolutely change the NPP settings on these cars WITHOUT starting the car. Hold the start button down until the dash lights up and then you can navigate the infotainment system and switch on Stealth Mode.

Not only would I love to see the stock exhaust, I would love to see actual measurements as a graph. There should be some level of standardized testing where specific dB levels could be measured at specific RPM's to be able to draw true sound level comparisons instead of being shown a graphic of the "perception" of the sound.
