I have a HKS mild steel d/p fitted to my car its a closed mouth design (a blanking plate over the waste gate on the turbo) which most people seem to dislike as they say it causes the boost to rise to much as the waste gate cannot vent gas quick enough (boost creep), but luckily i don't have any issues with it, and the car still makes good power.

As for the quality i have no complaintes there either, it's been on the car 4 years and when i wrapped it in exhaust wrap last year it had no rust no it to speak of.
