Meh, I live in Kalifornia and I pulled my fuse, my valves are 100% open 100% of the time, if you don't jump on it, you are WELL below 95 dB...

Even in Track Mode the NPP will close at certain RPM and throttle settings, the only way to have them open 100% of the time is either tune it that way or pull the NPP fuse (which is what I did) and they will stay open 100% of the time...
