Hey i actually got the lip of ebay this weekend and put it on
it was 155$ shipped and i do not regret it at all
you do not have absolutely any difference in the wind noise, it will not flap in the wind and its really easy to install
i thought it would be lower than the stock bumper but nope.
it is the exact same to the naked eye, i looked at it very closely and it only comes down 1/2 to 1 inch not nearly enough to scrape it on any curve that i met soo far
and i love the look
