I can see how people can get annoyed with the drone but so far it's bearable
I just installed mine two days ago as well. It does not drone as bad as people make it out to be. Then again I don't drive on the freeway at 80-85 mph (to preserve mpg during my commutes), so maybe that is where it gets noisy?
In any case, it isn't half as loud as my sentra spec v's exhaust. It sounds a lot better too.
