I also contacted them some years ago to ask for dyno charts and information on their development process. None available, just the same worthless assurance that they fit all existing link pipes/end cans and that no re-jetting is required.
I didn't bother to follow up with the obvious question as to how they knew no jetting change was required if they hadn't dyno'ed the product ...
The dyno chart I have is from someone who fitted a set of these headers and spent a lot of time and cash trying to eliminate a flat spot around 3 - 4k rpm. He eventually ditched them for a set of EXUP-equipped OE headers.
Says it all, really.
