Default Help ID'ing these LT headers

Like title states, I'm trying to identify these long tubes I purchased. I got them from a buddy who has a local corvette shop, his tech guy had them on his c5. They were a really good deal that included the xpipe so I went ahead and got them. They don't seem to have any stamping except for the #1183 on the top of the headers. Any help/leads would be appreciated!

Do you know if TPIS headers usually have stampings or anything?
