Broken Exhaust Manifold Bolt, What Can I Do? Options

[TRD-ST204]

Today I was looking around my engine and found that there was a exhaust manifold nut missing. So I looked closely and realized that half of the bolt was snapped off. What can I do to fix it? Is there replacement studs that I can use? If so how would I take off the broken half? Thanks

When mine broke, I had to drill the broken stud because it was about three threads inside the head. I drilled it and tried to use and easy out. No luck! Eventually had to drill out the old bolt and tap a larger hole. I was told to find a stud that had two different sizes to it, but ended up using a heli coil. (I am not sure if I spelt that right). I placed it in the one size larger hole and then placed a stud that was the same size as the rest of the stock ones. That was four months ago and seems to be holding fine.
