Four problems related to manifold/header/muffler/tail pipe have been reported for the 2014 Ford F-150. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2014 Ford F-150 based on all problems reported for the 2014 F-150.
The contact owns a 2014 Ford F-150. The contact stated that while driving at an undisclosed speed, the contact noticed a rattling sound coming from the hood. The vehicle was taken to the dealer where it was diagnosed with the driver's side exhaust manifold shield failure. The contact was informed that the driver's side exhaust manifold shield needed to be replaced. In addition, the contact was informed that the passenger's side exhaust manifold shield was in the process of failing. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 149,499.
Ford has obviously machined manifolds for the F-150 that are less than reliable and lack in quality. The exhaust manifolds are not hardened to endure engine heat and end up warping. This causes exhaust bolts to break, exhaust gaskets to be destroyed and in turn causes loud noises and potential damage to the motor on their F-150 trucks. Ford obviously knows that they have a problem on their hands as they are currently dealing with 1,700+ vehicles that are sitting in service shops across the country for this very reason. I called Ford to find out what was causing the issue and they explained that the materials just aren't holding up to driving conditions. Ford is working redesigning the manifolds and releasing them for purchase. However, it you have an issue this large and have admitted that it is due to your own failure to produce a product/part that will endure normal driving conditions, this should be recalled and fixed by Ford. Personally, I don't drive this truck very often. It is stored inside and taken care of to the extreme. The vehicle had been parked in a garage for a few days to a week (approximately) and when I started the truck I heard a loud "clicking" noise. I took it out for a drive to see if I could locate the noise. At first is was just a fast clicking noise on acceleration. This became a loud clicking mixed with a whistling noise. Thinking it was a bearing in one of the turbos, I took it in for inspection and they found the broken exhaust stud and damaged exhaust gasket. While working on fixing the issues, they found that all of this resulted from the deformed manifold.

Warped exhaust manifold resulting in broken manifold stud, exhaust leak and excessive engine noise.
