I have a set in the nickel-plated chrome that have been on there for 6 or 7 years, and they have been awesome. I've had the starter in and out twice without moving anything, I've never had a flange leak, they tuck up tight, and I didn't have to ding anything or even move the engine to get them on... and they still look decent, considering I'm not a detail freak that would waste a Saturday polishing a header. I basically put them on and have driven the crap out of the car.

I've said it before, and I'll say it again: When I was looking for headers I was offered a used set of Hookers, and somebody on here said they would pick up cans on the side of the road to get money for a set of TTIs before putting anything else on. It took a little longer to save the money, but it was absolutely worth the investment. They are flawless.
