Apparently, the exhaust manifold bolts are too small. heat and engine torque create too much stress on the rear bolts and they snap,"A- factory engineering flaw". the bolts are special, they hold a heat shield on, that attaches to the heads on the bolts. No apparent fix,other than re-design a bigger stronger bolt and re-tap the holes on the heads.
