Default Sounds like exhaust leak?

Got a question if someone can help me, I own a 05 f150 with 5.4 3 valve, and everytime I start it, doest matter cold or hot start, it sounds like the exhaust has a leak, and the engine runs rough for say 30 seconds then goes away. I bought the truck with 80,000 miles, it was well taken care of. You never hear the noise again untill you shut it off ,then re-start it again.
Any ideas? Truck runs perfect, good oil pressure, Lady that owned the truck used 5w30 motorcraft oil, changed every 3000 miles.
I thought it was a oiling problem, after speaking to my buddie that works for a Ford Dealership, he tells me it might be a CAM SENSOR, Ive owned 4.6 2 valve engines, they dont make this noise, any help ide be greatful!!

I have the same noise on mine i took it to get the oil changed and to get the works on my 2004 f150 5.4 Lariat and they said it is the exhaust manifold leak which they estimated at $1,300 which is rediculous and i would take mine to a local exhaust shop thats what im gonna do probally this summer when i have more money, but id get a quote before you have any work done!

The passenger exhaust manifold is a known failure.
I had mine replaced under a semi warranty.
Still cost me $480.

Yes do a search, the pass side is known for leaks from either warped or cracked exhaust manifold. And a pain cause it's also known for breaking studs upon removal. Good luck. If you do it yourself be careful and make sure you have an extraction kit handy. I did mine and broke the stud behind the engine mount. Was a pain in the ***!

Came with my truck, cracked manifold (right side)... Hopefully that's not your issue, but if it is then I'm sorry. Cost me close to $900
