Every exhaust drones. It's a natural occurrence due to physics involved. What's important is muffling, or minimizing the drone or the shifting of it's frequency to acceptable/tolerable levels. Whether or not you agree it's still true. Glad to know NHP minimizes it to very acceptable levels w/o muffling sound too much. OEM's make it tolerable by muffling the sound immensely.
