A sawzall with a metal-cutting blade make the cuts pretty well, but for the corners I resorted to the hacksaw because the sawzall likes to jump out of the cut while you're making it.
I would go back and widen all the cuts to the width of the sawzall blade because I've been told of firsthand accounts where the cuts (made with just a hacksaw) were skinny enough that they fused together with heat.
Is the middle cut really only supposed to go halfwayish through in the link posted?

If you are replacing the studs and nuts, just take one out and take it to the Hardware store with you, and get the same size stud, nut, and lockwasher, Or Stud and locknut
IIRC they're 8x1.25 exhaust studs and the corresponding nut & lockwasher OR locknut.

You go to the parts store and look for the exhaust studs that say "8x1.25" on the baggie. They're a little over an inch long.. and they'll probably be black...
If you can't figure that out, go to the guy behind the counter and ask him where the "grade eight, size eight by one-twenty-five millimeter exhaust studs" are.

M8 is the size of the threading.
You'd want (4) M10 studs for the manifold to turbo flange, IIRC.
1.25" is the tread pitch. So look for M10x1.25 Grade 8 Automotive Studs.
You'll want M8 for the turbo to downpipe.
Make sure they are long enough so you can fit your new nuts on them, but not too long that the stick out and get in the way of mounting things.
like this:

Dont take my word for the sizing, bring the manifold and turbo with you and make sure. ACE hardware sells everything you need.
