I am working on replacing the flex pipe on my 97 b4s. My friend has a welder, and we are trying to remove the down pipe from the turbo. We removed the axle for access, and the bolts are still stuck pretty well. We have heated them up with a propane torch and tried to remove with a ratchet. They weren't quite red hot. We tried 6 point 13mm (too big) and 12mm (too small) and found a 12 point 12mm will hammer down onto the nuts, but they feel like they are going to strip. I am thinking of making a small cut along the base of the nut where it seats on the turbo to relieve pressure and try again with the ratchet. Does anyone have any other ideas of what we can try? I suppose we can cut the nuts off but then we would have to drill out the studs...
