And coming from a drone ridden 5th gen, I really like both the NPP exhaust and the lack of drone.

How the noise cancellation works, is that there are two microphones, one in each door, that listen for exhaust drone. The audio signal comes off the head unit and goes back to the amp, but not in an audio signal that you can just easily tap into. When it gets to the amp, the noise cancellation signal is added to the audio signal and and sent to the large speakers in our cars (on my vert it is the front doors and lower rear panels). So if you add a sub, and try to get the signal post-amp, it will include a noise cancellation signal. Putting the signal through a sub will actually create drone instead of killing it.

So if you want to add a sub and keep your noise cancellation, with NPP or regular exhaust, there is still no solution. I am glad to hear there is a box for the coupe, maybe the convertible won't be far behind.

Is anyone working on a solution or is this just a dead topic?
