Actually, it is a very quality piece that fits flawlessly. I saw one on a Grabber Orange car with some other Boss accents and it looked awesome. The other thing is that it is speed tested by Agent 47 and the flow-through won't affect the handling of the car.
I bought the Shelby grille. Cost me over $100 for the surround and over $100 for the insert. I believe they were $249 complete for a while back when I got mine. Thing is a complete chinese piece of crap. Got it with a gray injection molding blem. Also, when installed, the hood wants to fly off at 65mph with a head wind.
I know the Agent 47 stuff is made here and quality. They are an offshoot of a plastics company and basically make high end plastic components for another industry. I will swear by the quality and customer service. I have their mirrors and couldn't be happier.
