For my '82 Caddy, I'll be using a gas dual downpipe manifold, just drilled out the metric threads in the existing EGR (or O2
sensor) hole and re-tapped to 1/4" NPT, using an ISSPRO EGT.  All I have left to do is to put the manifold in.  The ISSPRO kit
is nice since it has the thermocouple buffer amp that can go in the engine bay.  Then it is just a couple of wires up to the
