This is a pair of Doug Thorley Shorty (Ceramic Coated) Headers. I purchased these used, mainly just for show purposes. These function fine, but have typical scratches from being installed (I got them that way). The good thing is most of the scratches are on the side. You really just see the top once installed. I am just selling them because I finally went to LT's.
If you need a set of mounting bolts, I will include ones from my stock manifolds - which is what I used. No gaskets or other hardware included.
Here is a link to them on the Doug Thorley site. Part # THY-336-C (fits L99 or LS3): http://dougthorleyheaders.com/products/productID/1031
