While that's how ANC should work, how it really works with the mustang doesn't seem to be the same. The system is listening for very specific frequencies given off by the stock exhaust system. Aftermarket exhausts do not produce those same frequencies, at the same length or in the same RPM range, so it does not cancel the sound wave as it should. Regarding sub woofers, the microphone is not at all hearing the sub woofer and getting confused. How do I know this, because you can can turn the volume to absolute zero on the headset and it will still send the noise cancelling wave which you'll hear coming through the sub woffer. This signals the car might perhaps be sending 'some' pre-sampled waves as it tends to happen on specific RPM's in conjunction with also listening.
