I bought these LS Headers used for my C5 and turns out they don't fit. I was wondering if anyone can identify them from the pics. I don't have a part number.
I measured them and they are 1 7/8 to 3 with a 2 1/2 adapter welded on to mate to the stock exhaust.
Any thoughts ?
I don't know if anyone is good enough to look at a set of headers and know what they fit. I'm not a mechanic but I did notice the the O2 bungs are on top of the collector. Maybe for use on the dyno?

Thanks for the response. I figured there would be some forum LS gurus who may be able to identify these ?
I dont think they are, but I could be wrong. The center bolts holes on mine I dont remember being at different angles
I am positive they will fit an LS1 head. The guy I bought them from said he got them if a Z06, but when I posted in the corvetteforums guys over there believe they will not fit a C5.
The only headers I personally know of that have an 02 facing up is 07+ trucks. Fbody headers have a pretty good S shape on the drivers side but the passenger side is more laid back and slanted (overall shape). Those being symmetrical seems like maybe they are dyno headers, or at least not for an application i recognize. Dont rule out g8s, GTOs etc. Lots of stuff came with gen3/4 engines. Could be any of those applications.
The O2 bungs on GTO headers come in on an angle to clear the floorpan/chassis rails from the inside near the bellhousing. C5 headers have a nice angle to them as they contour under the torque tube bellhousing and direct down the tunnel. I would second what 01ssreda4 said, they appear to be dyno headers, however 07-13 Truck or G8 both have O2 bungs that face up.

That was exactly the red flag that I noticed to ensure that these are not f-body headers.

Are these F Boby headers ?
