That's their ad - "the no-drone system". I've had Corsa in the past on other cars and, frankly, it wasn't all that great. Their hardware frequently broke - I snapped some of their bolts in half no doing anything all that unusual. Plus, it did drone. I don't think there is any such thing as a "no-drone" exhaust - they will all drone at some harmonic level. It depends on the owner whether they "like" or "dislike" it.
