I had an 2010 Ram 1500 that loved to break exhaust manifold bolts, I had the bolts replaced twice on the passenger side (new manifold the 2nd time) and the drivers side once but it was going to need them replaced again. I sold that truck to a friend and told him all about the issues I was having, gave him a good deal on the truck and he was happy to drive it away. From what I understand, Ram has not even attempted to fix the issue with the 5.7 and exhaust manifold bolts continue to break to this day.
Too much emissions hanging underneath these things. Get rid of huge factory mufflers, cats, resonators and such and you wouldn't see near the breakage of bolts.
Betting even just swapping the factory muffler for a smaller performance muffler would lose 20 pounds.
