I got 2 of the OEM ones from Bernardi Honda, for our 2015 Tourings, when they had a free shipping (black friday) promo last year. Some of the ones on ebay are plastic only and not painted to match the vehicle color. Some of those clip on. You do have to drill a few holes in the roof of the vehicle, for the OEM product, but it wasn't too bad We did both installs at the same time. Here is the end result. I like the look.
They were $214 each, with shipping, from Bernardi. (a year ago) The 2015 and 2016 are identical, so the part numbers are probably the same. (paint code is part of the part #)
