Loud noise when decelerating

When I get up to 6k rpms and let off the gas and let the engine slow the car down there is a really distinct vibrating noise that sounds awful

Is there a way you can take a video of it (safely)? You will get some people here that will want to hear the exact sound to be able to pinpoint what is wrong with it.

I think mine might be doing something similar but yours is much louder, will have to test driving it like you did in the video

You may need to find a mechanic-type person to take it for a test drive. Very hard to diagnose noises over the Internet unless they are very pronounced. If you buy/rent/borrow an OBD scanner, you can monitor AFRs and such and maybe get an idea what's going on.

My dad used to be a mechanic and he has an OBD, but he's out of town and he's the one who helps me do all the mechanical stuff with my car. I was just trying to see if it was something I should worry about.

Sounds like it might be the thin aluminum heat shield thats right above short tails. Mine was making noise so I removed it. No problems. I would check that first
