I'd like to cast my vote that the A.I.R. tubes and the O2 bungs be at least an option......In the Republik of NY the state inspection of your emissions' system includes a visual exam of all the parts, if it isn't there you fail.
I would gladly pay to have those added to my set by you guys, rather than me trying to find some one to install that stuff after I buy the headers. Thank you for efforts on this deal!
