identifying headers

They have slipfit collectors , had emission fittings , are ceramic coated, and the #8 tube comes out of the collector. Any help would be great even better if you could tell me what y pipe fits them. thanks
the pictured ones look like the Headman but are not stepped, and headmans do not come with the air and EGR fittings to my knowledge
