Did I get ripped off?

I bought that GT3 bumper and was told it was OEM, but its seeming likes its not. It seems like fiberglass. There are no license plate holes ( i guess a good thing) and there isnt a tow hole. There is fiberglass weave on the inside too. It looks like a good bumper though, an EXACT replica to say the least (the air intake vents look perfectly contoured to the air intake vents on the radiators, all tabs look correct, and looks good overall). I paid 400 for it, is that still a good deal for a fiberglass bumper? Buyer beware I guess.
