Only you can answer that question, so much of it is personal preference. But you paid an extra $995 for NPP, so you might as well leave it as is and drive the car for at least a few months to see what you like.

I've got very few miles on mine thus far, but have noticed that different drive modes make a difference in how quickly the valves open/close based on RPM, etc. The nice thing with NPP, in my opinion, is the ability to have it loud when you want, yet being able to put it in stealth mode when you'd rather not be. I also like that it is "get your attention loud" but not obnoxious. In my opinion, something akin to the low rumble of a Harley vs. the whine of crotch rocket racing past.
