So after looking at these headers for 1+ yrs, I finally made the plunge and the took the risk on these since there seems to be very little info out there on these headers. I've wanted to try a full catless setup so this is two mods in one for me.
Got these for ~$1k on ebay.

Currently I have test pipes (stock secondaries still in place), ms intake, bpm stage 2 tune, cnt exhaust.
I'll be installing these myself on my lift.
I'll document the process.
Notes on the install are on my blog, there were major issues with the length
pbonsalb &
SAMM3Y called it, the end of the end pipes were too long on one side and required cutting, pictures in part 2 link below:

Update #2 Headers have arrived.
Quality seems pretty good, header flanges look good against a straight edge no warpage. The parts of the mid section that is 3" do seem pretty big in person.
Final Update:
Conclusion, Becker Performance Headers & xpipe made +15whp / +8wtq over test pipes. Dynos where done within a week of eachother, using the same tank of 93. Conditions were 93F & 96F. ~40% Humidity
