Manifold/header/muffler/tail Pipe problem #1

The heads of the bolts that hold the exhaust manifolds to the cylinder heads are breaking off for no apparent reason causing an exhaust leak.

Manifold/header/muffler/tail Pipe problem #2

I have had a exhaust leak that I finally pinpointed to be broken exhaust manifold bolts. The truck was bought new by me and has never had any exaust work done. Now I have to take it to a dealer to have this expensive repair done. Apperantly this seems to be an extensive problem, with these bolts. This I understand to be an extensive repair. Gm knows there is a problem with the bolts, why wont they make it right.
