If you're talking about the TTI headers, they have been out longer than ten years. I bought mine in either '08 or '09. I've never had a problem with mine, great fit and they still look as good as they did when I first put them in the car.
I'm not sure what it is about mine. Granted my car also sits outside all the time, albeit under a cover, but the coating has not held up well for me at all.
