Yup, no doubt, that sucks. :-(
Don't give up though. Someone else here on the forum had a broken stud same problem and hopefully they will chime in. If I recall they had to pull off the downpipe/converter and then they removed the broken stud and replace it with a new bolt. Not sure if they drilled out the old stud or used an easy-out.
Most manufacturers/dealerships say "non-servicaeble" when one of two things occur.
1. They lack the initiative/ingenuity to fix the problem
2. The labor costs at $100 an hour make it cheaper to replace the complete unit.
Good luck and report back how you solve the problem.
