Loud rattle at low RPM in 1st Gear

Hey y'all, I've got a rattle when I'm in first gear and creeping from a stop or slowly uphill. I have a 2009 2.7 5MT 2WD. The rattle started last year and has not impacted driving capability. I have been looking for a loose heat shield but have not found one yet. Listen to the attached videos, the rattle is most noticeable at the end.

I don’t know what the rattle is, but I definitely know what the squeak is……
Clutch pedal

Brings back memories.

 

It used to be worse lol, the squeak is a constant

 

Driving in to work this morning and I had the fan blowing and it became more noticeable, ring any bells?

 

With some persuasion of a rubber mallet, I traced the rattle to the spring loaded manifold bolts that hold the exhaust to the header. The header wasn't seated properly and the bolts had wiggled free a bit. I adjusted it and cranked down on those and, voila, the rattle is gone!
