Looks like they are factory installed

Had to reorder as first set didn't fit quite right. Something to do with factory fairings. Second set fit great on rear, but front set has a gap between flap and fairing. Believe the first set of flaps would have been better fit. Great outfit to deal with, and exchange went smooth, although longer time frame. I like them, looks good too.
