Does anyone have a pic that they can msg me showing where the EGR is on a 1990 Mu, Looking at removing (or disabling), ..
I think its the 2 diaphram looking things off the intake manifold... but would like to be sure...
Cheers in advance.

You are correct, plus there is the pipe that comes of the exhuast manifold near the back of the motor.
Just a tip, use at least 2 to 3mm plate to blank them off with as anything lighter can flex under the pressure and leak.

Just a quick question. I plan on using 3mm steel in the exhuast manifold, and 2mm ally where the EGR is. Sound okay? Also suggestion on type of sealer to use on the EGR plate, all i have is "Gasket Goo".

The exhaust side is far too hot for gasket goo Manseal or similar would be better Gasket goo will be ok on the inlet side but I would prefer a flexible sealant like RTV. Go 3mm aloy for the inlet. If it leaks it does no harm on the inlet but everyone within 100meters will be looking for the siren under boost but as soon as you stop to look for the noise it will be gone. (been there done that).
I used plain gasket paper on mine which was a lot better than the original steel gasket used by the shop. If you want enough gasket paper come round and I can give you enough

Google EGR and you will see what it does and how it works. The main purpose of EGR is to lower the combustion temperature so less nitrous oxide is formed which is a major part of smog. In theory this lower temp makes the engine less efficient so it uses more fuel and has less power but in practise as long as the EGR is working properly the difference is nearly impossible to measure unless you do lots of round town running. If its faulty the car runs like a pig or worse.
A side effect of EGR though is due to the recycled exhaust which can partialy block the inlet with soot over time causeing low power as you have less airflow
