Help, broke EGR casting!

Help, broke EGR casting!
In trying to disassemble everything to get my fuel injectors out for cleaning I broke the EGR valve casting at the junction with the pipe going down to the exhaust manifold. In hindsight I should have just unbolted the EGR at the intake manifold, but too late now. The broken casting needs to be removed from the upper pipe fitting. My problem now is trying to remove the pipe at the lower end where it screws into the exhaust manifold. Tried penetrating oil and heat (MAPP gas) with no luck so far. Are any of the freeze products any good? Any other suggestions? I'm really paranoid now about breaking the lower fitting and compounding the problem. Thanks.

There's a youtube vid where the guy blazes that lower nut to red hot before he can get it loose...
I'd recommend hourly doses of pb blaster and daily tweaks with a wrench to see if it moves. 5:00 into this video:
