Pics of EGR modification for L98 heads
I got the pics of what I did to my headers to make the EGR work with the L98 heads and TPIS intake manifold. Keep in mind this only works on a stock Corvette, or any aftermarket intake manifold. A Camaro/Firebird stock intake does not have the port on the back for the EGR. These are SLP 1 3/4" headers, specially modified.

I wont have to smog again until November 2002, so I have time.
I emailed my smog tech friend (he knows who he is) and asked him about this setup, and he said he wouldnt bat an eye at it, and I shouldnt have any trouble.
But if I do, I can get the car certified as a 91 Corvette.
