This would not be a big deal if it was just exhaust pipe, but its before my turbo. So I don't want anything inside the pipe that could brake loose and mess up my turbo. How can I get the welding wire out of the pipe. Its got a couple bends in it and so on so you can't see where the wire is. But I know its in there and I need to know how to break it loose.
    You can fish towel through tube and pull it back an forth to see if it hangs up on the wire. But, about only way to really know how welds look inside your exhaust manifold is looking with fiber optic bore scope. See them on page 80, & 81 Sears 2009-2010 tool catalogue. Harbor Freight also sells them. Because I don't have a bore scope. I would cut out 1 or 2 welds on suspect tube with Dremel cutting disc to remove tube section to see and eliminate suspect welds. Then reweld exhaust.

      No big deal. Grinding out your bad welds and welding it again is part of welding. Isn't ethical to leave bad welds that will fail.

        Is it possible to get a long chisel in there and knock it out with a hammer?
        If not, you will have to cut out the weld, clean it up and re weld it.
