The only other thing I found out was that the '87+ version (which still fits my '85) moved the EGR pipe connection elsewhere (the side I think) which might have been Toyota's answer to the problem. They never explained why they did that. That part was $100 more than what I paid for my part and it also meant that I'd have to get a new EGR pipe, etc, etc and I just didn't want to deal with unknowns.
Oh well, when the new pipe cracks I'll post an update for the archives so we can see just how long these things actually last.

I just ordered the exact same thing from Aaron yesterday - for the exact same reasons. This thread couldnt have been more relevant to me.
Ceramic coating on the outside of the mani wouldnt that trap more heat in and make the internal temps hotter?
