I am biased to it because I had one. I have to say it is just like the rest of the headers on the market. It fits very well.(install was simple) there were no real noticablepower gains, but the car did feel more responsive. I had it on my car for about 5 months or so. It does produce a good amount of rasp at higher RPMs(as does most others as well)I would also say the quality is pretty good, the welds look good and it is stainless steel.
If you need a more info/review on it just ask and I can provide more info.
I also have one for sale. I took it off for my turbo fund.
