Unless you've replaced seals, most of the AC's are empty.
The biggest thing to removing the EGR pipe is LOTS of knocker-loose, or other penetrating oil.
If you can spray it and heat it up a couple of times, repeat after it cools, it will help loosen it up.
Don't break it! I don't think any are available anywhere, so cleaning from the top may be all you can do; use a small ~1/4" brush to clean, while spraying or pouring chemtool B12.
There's a washer welded between the two small tubes, so be careful.
That orifice has to be clean to work. And the tiny tubes.
That will flush all the crap into the exhaust, so you might want to loosen that side up so it drains.
It ain't going to be good for the cats, it's a blob of oily crap.
Disconnect the removable piece where the egr goes into the intake; it has tiny passages that get full of crap.
Try NOT to send anything into the engine; it won't like it.
A good seafoaming afterwards can help clean the exhaust out.
