Another Exhaust rattle...solved

So when I bought the car it had a horrid rattle that was the usual cat heat shield falling apart.
As time went on a persistent rattle that seemed very obviously exhaust related, like you forgot to tighten a clamp but it resisted all my attempts to find it. Started chasing ghosts, replaced the serpentine belt idler pulley, rebuilt the supercharger, just in case...put a different exhaust.....

Put urethane motor mounts and it became nearly constant.

Finally I had it on the lift and I am looking around and there it is.

Support bracket for the exhaust manifold. One nut and silence!

It is a pretty crappy welding job, I assume a Toyota part, hopefully it is not really needed with a shorter exhaust system in this car. I have a spare manifold I picked up cause I wanted a spare cat, weld is the same[stupid robots]

Vertically centered horizontally just center right you can see the shiny bit where the bracket is broken and polishing itself

Here's what my car looked like back in May 2019.

Luckily no rattle but now I'm ready for one.
