    Found the source and fixed it in 3mins. Apparently the bolt closest to the firewall that holds the heat shield in place for the exhaust manifold has snapped off. So the heat shield was rattling against the manifold. I took a pry bar and pried it back enough so it wasn't making any contact- noise and rattling gone. So glad I just saved myself $250.

    Now what's my move with this? Let it go? Idk how I'd repair this... Unless I replaced the manifolds and fixed it then.

    Pull that manifold, weld a nut to what's left of the broken manifold stud and back it out. I had the same issue. It's very common for that bolt to snap on the 4.7
