Ratting noise under car?
hello, i have a 1993 RHD FD,
whenever i start my car, sometimes ill hear rattling noises under the car. it sounds like metal clanging each other, it doesnt matter if its idling, or if im driving, it stays the same throughout. car was rebuilt about 3 months ago but the sound was still there before and after the rebuilt. car drives awesome. also it sounds like its coming from the middle of the car? its super annoying.. please let me know if anyone has some insight for me! thank you
heres a video of the noise

Definitely get the car on jack stands and get under there with the car cold and shake, grab, and pull on different parts of the exhaust.
I can't watch the video now but I'll check it out later.
I've seen one of the aluminum tunnel braces installed upside-down and backwards before which made the exhaust hit it and cause all kinds of funky noises. Could also be loose material in the cat, broken heat shield, missing exhaust hanger, or broken PPF as stated.

As far as a motor mount check the only way i knew mine were bad is i was resealing my oil pan and seen my drivers side was in 2 pieces once i dropped the subframe. I seen this is super common even on low mileage cars but if you just had the motor out then it is impossible not to see they need replacing. Maybe to double check make sure there is no fluid leaking out of them. Im not sure if you could use a pry bar to check for movement between the motor and subframe. My engine didnt rock too much either so i would never have known unless i dropped that subframe or the passenger side one was bad too.

Finally got to listen to the video. The sound does sound like something internal, like broken material in the cat.
If you don't find something external it would be worth pulling the cat and having a look inside.
