In Stealth mode, I don't think the NPP valves will open under 100% pedal operation like it would in Tour, Sport, and Track modes. The owners manual specifically states not to run in the Stealth mode exhaust setting during track operation. With that said, I think there would be a power difference to some extent at high exhaust flow operation (ie. high engine speed & high load).
