Annoying problem

My 2004 f250 v10 has presented an annoying quirk. At around 1500-1600 rpm I hear a vibration that sounds like an exhaust heat shield rattling against the engine or exhaust itself. If I decrease rpm it goes away and if I increase it comes and goes. Ive had the truck on a lift 3 times looking the heat shields and anything else I can think of to no avail. Has anyone else ran into this or have any ideas what else to check? This is really aggravating! Thanks

Check your exhaust manifold studs.

I removed a heat shield near the y pipe on my 99 V10 for this very reason.

Check the tq converter cover plate. Mine was rattling/buzzing so I but a slight bend in it and reinstalled it. I also had a heat shield on the crazy Y that was broke on one end.

Mine used to rattle a long time ago, when I replaced the aftermarket muffler the previous owner had put on the muffler guy tack the plate in several places.
