My friend has a 2003 RSX Type S that does the same thing. He could not figure out for the life of him why it would pull to the right, even on a road with the crown going to the left.

He brought it to the Honda Dealer, and they diagnosed it as frame damage. It was perfectly aligned, but becase the chassis was tweaked, it would not be true. Perhaps this is the case with your car. Have you confirmed and ruled out all other possibilities? I would make sure that everything has been aligned perfectly, and make sure everything is tight and trouble free.
