Rear Insert Question

So I ran across this website: http://www.jhpss.com/Pontiac-GTO/bumperinsert.htm
How legit is this website? And does anybody have any experience with these inserts? Do they fit on an '06 GTO perfectly? And do they look OEM?
If not, can someone point me in the direction of a 'bang-for-your-buck' rear insert?
Thank you in advance!
Another option is the Maverick Man rear diffuser. It is a little more expensive and will take some time to be shipped, but they look great. They come in fiberglass and carbon fiber: http://maverickmancarbon.com/archives/766

I think it looks sweet, I'm just always so gun shy about putting non OEM exterior parts on my cars.
Do a few searches over on ls1gto.com and you'll probably find a few pics of one. There is probably one in this thread http://www.ls1gto.com/forums/showthread.php?t=130812 but I'm too lazy to search for you, lol...
JHP is legit
