My own Hemi experience (2004 2500 w/5.7) it was a cracked right side exhaust manifold and a couple of broken studs.
Think cracked exhaust manifolds and broken bolts are due to all of the BS exhaust cats, resonators, huge mufflers and whatever else they think manufacturers need to use to cut emissions. A lot of extra weight hanging around down there.
30+ years ago a cracked exhaust manifold or broken bolts at the head were rare.
