Thanks for all the replies. I guy has a set of these brand new for $475 or should I just keep searching for some used TTI's in 1 7/8". Not in a huge hurry for headers as I'm STILL waiting for the machine shop . Once they do their work, then I'll order up the kit from Performance Only. someday...
Here's the headers I can get for $475-->>

edit:
Maybe I can make a road trip to Indy this weekend for the trade show to see what all is there. doubtful, unless I can find someone else to join...
