Exhaust manifolds both warped. Poorly designed and few studs near the end. Costly repair and very involved install.

A stud on the driver's side exhaust manifold sheered off creating an exhaust leak and an associated noise, like a squeaky fan belt noise, from the leak. An exhaust leak of this nature could effect the emission controls of the vehicle creating additional pollution to the atmosphere, and endangering the occupants with Carbon Dioxide (CO) gas inside the truck's cabin. And, in states such as California, the vehicle could fail smog tests. There were no warning lights or messages from the system computer indicating there was an emission problem, yet, and the noise can be heard while accelerating at any speed. I drove with this problem for over 7,000 plus miles before contacting my dealer with problem, thinking it was only a belt. On August 30, 2021, I finally took it to my Ford dealer to diagnose the problem, and was quoted an estimate of over $2,100 to repair the exhaust leak. The truck was of course out of warranty and had 75,074 miles on it. I had to wait two weeks for the parts to arrive, and another week for the repair to be completed. The truck was finally repaired and returned to me on September 23, 2021. But, I was also informed, and the service order states, and I can detect, another exhaust leak coming from the passenger side of the engine from the other exhaust manifold. I haven't received an estimate yet, but I have to assume the cost will be similar. I searched the NTSB Web Site for any recalls or TSB's for this type of situation, and found similar incidents to mine, but no recalls. The service manage at my Ford dealership was not aware of any of these type of problems, but the service writer did state to me they had other trucks in the shop with the same type problem. I see this as a health and safety issue as Carbon Dioxide gas could affect the driver and passengers of the vehicle creating a life threatening situation and Ford should issue a recall to repair these trucks and reimburse owners who have had repairs made at their own expense.
