Geezz.. I have not read any comments about NWOR or Downey in years! I didn't even know they still exist.
I like LCE's quality and the 1/2" main flange. DT's quality, or lack of, has always been a point in discussions.
As I mentioned, unless or until I can see a certified dyno test comparing an LCE and a DT header, the difference is mostly speculation and opinion to me. I have my own experience to go by, but its still just opinion.
