What did you do ? Left hand drill bit etc..
Swore - a lot. I do not think this actually helped any but I felt better.
If it happened again the first thing I would try is to use a Dremel to cut a slot
then use plenty of release oil and some heat before using a screwdriver to try and undo it. An impact driver might work better but may just chew up the slot.
I drilled mine out but had to use a right hand drill as I did not have a left
hand drill (I am going to get some). I found an offcut of timber and using the
exhaust marked where the studs are. I then used a pillar drill to drill holes so
that it would fit over the back 3 studs (8 mm) and act as a guide for drilling
the front stud. You may have to grind away part of the stud so you have a flat surface to drill against and 6 mm would probably be a good size to start with.
I managed to create a hole and get it part threaded as I did not have the proper taps. I put some chemical metal into the hole and fitted the stud. It seems to be holding but I did not torque it up to much. I also reckon that as the headers are all in one piece the other 7 good studs should help keep everything in place.
