Rattle when not on the gas...

[Fkyx]

Alright. So I searched for "idle rattle" and didn't find anything that matches my situation. When I turn the car on and let it idle, there's a pretty audible rattle coming from the vicinity of the cat. When I rev the engine, even the most minimal amounts (up to 2k), it stops until I let off the gas, then it continues to rattle. I also noticed it rattles a little bit when you let off the gas while driving.

I just wanted to know if it's most likely the cat or whether it could be something else not exhaust related.

Heat shield. Remove or clamp tight with stainless band clamps.

my car does that same thing, but sometimes it wont do it for almost a week, and sometimes it does it every time it idles

i think its just a heat shield, havent looked into it too much, if you cant figure it out by monday ill put my car on the lift at school and check it out
