I have repaired two broken manifold studs on our daily drivers by welding a 
stainless steel bolt into the remaining slot where the original stud was 
threaded in.  In both cases I needed to clean up the area with a grinder to 
get the bolt to fit snugly and to clean off corrosion for a good weld.  I 
used nickel-based welding electrode specific for repairs to cast iron, but 
I suppose brazing would work fine.  It is good practice to clamp or wire 
the bolt securely in place and thoroughly heat the end of the manifold 
before welding it.  I pulled the lower shroud in each case and attached the 
welder's ground clamp farther up out of harms way.

Apply anti-seize compound to the bolt (now a stud) and secure the exhaust 
with a pair of brass nuts (jammed together).
