You can try using a masonary carbide bit. Lowes or Hmoe Depot will have them. Get a few 1/8" and give them a try with some cutting fluid. Don't worry if you wind up off-center. Worst case you tap it, make a plug out of aluminum, thread it, insert it and then cut it off flush. Position your Y pipe to locate the hole, and then drill and tap a new hole through it. If you have a small torch you can heat the broken piece up and then try loosening it with a small centerpunch. That might work. E Z outs are really E Z ins, they are very difficult to get out! I try not to use them, I never had much luck with them. If the bolt is that stuck that it broke off what is the logic of using an E Z out?
