So I was taking off my heatshield over the exhaust manifold last night and one of the bolts snapped off in the manifold. What is the easiest way to get it out?

I went ahead and reinstalled everything, And the shield doesn't rattle, but I need to get it out.. Is the best thing to do just to drill it out and use a bigger bolt? Ive never broken a bolt before..

Thanks in advance..

 

You can try drilling it partially, soak it with pb blaster and using an ez out. Otherwise drill and tap.
