My 09 mdx makes this annoying rattling noise when I accelerate, around 2000-3000rpm. I've researched and it seems to be heat shield related. I've checked heat shield on Cat front and back, it doesn't seem to be loose when I grab it to check if rusted loose.Does anybody have a diagram or pix on where I should focus on? thank you.

You can also check the middle shaft shield (I believe there was a TSB for it?)
The middle shaft connects the transmission and the passenger CV Axle, It has a shield on top of it.
