Hello, I am currently going thru fitting an LS2 into my 65 Vert. I am using 2003 C5 exhaust manifolds. Does anyone know of a source where I can buy the 3 holed flange that would bolt the Exhaust tubes to the Manifold? Seems like the C5 manifolds have an odd shaped collector flange that none of the typical parts stores carry.

Thanks for your help,

Matt

 

A few months ago I was looking for those flanges and had trouble finding people that had them. Perhaps try Stainless Works - I think they might have had something, but it was expensive.

Here is what I would do: Go on eBay and find someone selling a set of the early vette exhaust manifolds - they are made of steel instead of cast iron. Cut the flanges off the steel manifolds and put on a standard 3-hold flange. I know for sure that 1997-98 vetes used the steel manifolds, and I think some of the later ones did as well.

Are they the same as the trucks use? If so I have a pair. PM me if you want them.

 

I made my own out of 3/8" steel
