I welded mine shut in the past. I think you could just cut out a piece of aluminum, and drill two holes in it. If it is the same as my 97', I could make up a couple.

I have seen post the claim this will cause the tubes to break off and it is best to weld it shut. Anybody have info on this?

What's the purpose for blocking this off? Is it the EGR valve? Does it exist on the LS6?

That is what one of the header companies told me yesterday when I was calling around looking for plates.

I made my own so I guess I'll find out.

There is no EGR on the Corvette, this is AIR.
