Default Header ID Help



Hi Everyone - I have a set of headers that were given / willed to me. I was told they are C5 Corvette headers but they have a bracket that goes on the end of the headers as what looks like a reducer. Can anyone tell what brand they are? No part number to be found on them.

The AIR flange in at the rear. I'm used to seeing it in the Y. There is a threaded hole for what I am assuming is for an EGR. C5 doesn't have an EGR.

Thanks Rob - I will look closer tonight when I get home. Do you know what brand makes that bracket/ reducer by chance?

look like c5 headers to me.the air flange at the back is for the early c5.the 97-99 and maybe 2000 had the air tube in the back ,2001-04 had them on the next one in.the treaded bung is for the oil dipstick to bolt to.
brand,i don't know.never seen a set with that bracket.

^I thought the earlier models had the AIR tube there but wasn't sure.
Maybe they are OBX headers.

OBX, Stainless Works, Dynatech... do a Google search for images and compare. They look similar to TSP but for the fittings... and that crossover tube is crazy looking (although I'm sure it would work OK).

Well I appreciate the help.. I looked last night and the AIR on the left is one cylinder to far back for my 2001. So it must me for a 97 to 2000 before the LS6 intake and a little more HP was given. So now I have a pair of headers that I do not need.


Thanks again for the help guys! Merry Christmas.

find a 97-00 parting out and get the passanger air tube from it and change yours out.when i had my 99 i had headers for 01+ so i just changed the air tube.you have to pull the intake manifold to change it but that's not to hard.

if you don't have to worry about smog you can just get of the air stuff and block off the hole in the headers.
