It sounds like injectors on the top, cats rattle below but there’s another sound in there, I can hear it more on the drivers side in real life, between injectors and cats. Kinda sounds like brushes moving stupid fast on a floor or a little choochoo train in there. You can hear the cats rattling but that frequency is WAY less per second. Cats are like 1hz and the other sound I don’t recognize is like 200hz.
Any ideas? Thank you!
