"The 4-2-1 german manifolds found on late Golf/Jettas works VERY well."

Is that different from what I have on my '87 GLI? It's cast 4 into 2, then the downpipe is 2 into 1. Is there a better OE setup?

"These manifolds and downpipes are not tapped for an OXS sensor...that is in the cat."

So if I want to move the O2 sensor to someplace where it will get hot enough, I'll need to weld a bung into the collector area of the downpipe. I was hoping there was a good OE manifold with a provision for the sensor.

Sounds like I need to get the jackstands back out.
