I have them and so far they've held up well. They make pretty good power. Keep in mind the numbers in my sig were made under terrible conditions. The IAT was reading 112 degrees (110 degrees on the wall thermometer) and the dyno was not corrected. So I'm guessing with good air it would be in the 380-390 range through cats. Not bad for a cam and headers. Fit and finish is nice. Installation isn't to bad. Having a friend work them in from the top while you guide them in below makes life a lot easier. For the money, I would give LG's headers a serious look. If I had to do it over again, I'd be tempted to go that route.

I picked up a solid 25 rwhp and 20ft lbs of tq across the entire rpm range. This was on a 99 Frc with only a black wing and PRT exhaust and cats. 335 RWHP
A month later i got the car tuned i made 344 RWHP.
Now with my 382 it makes 460 rwhp and theses headers rock.
