Rattling sound near shifter area

Hey guys ever since I got back from training. I hear this weird rattling sound around 5500 to redline when I get on it. I rarely push the car to redline and I don't beat on it.

I have a rrm CAI and rrm udp. The sound was happening before I put both of them on.

Here's a video.

Its the part where it kind of sounds like motorcycle. I hope it's nothing bad.
Btw lmao ignore the end of the video. It was a clip for my twin brother and he just wanted to her the sound of the intake. And I was making a joke about the car being heavy because I had just filled the gas tank up lmao

I'm thinking it might be a bad rear motor mount, what do y'all think?

Lmao yeah and I can't wait to hear how it sounds after I doing a stage 1 or 2 cam. Still debating.

It's the sound right at the 3-4 second mark.

Some reason it seems like it is the motor mount because my wheel hop has gotten progressively worse. Or could it be a messed up catalytic converter? Lol. Idk! =(

Jeez, I know I've said it before but everytime someone posts on here about something wrong with their car, it's more than likely always directly related to excessive speeding.

Which is why, I drive like a grandma

Uh I wasn't speeding excessively lol. That was a pull on the highway with a speed limit of 75mph. I went up to 80mph and then slowed down.

It was a drop to 2nd then to third and shifted to 4th gear and slowed down after shifting to 4th.

I believe the cat or resonator is located directly below the shifter area. maybe you have a leak or something internal of the cat or resonator is loose?

some of the baffles in my muffler are loose and it buzzes above 3000 rpm

Ok yeah that's what I'm thinking it is, because the motor shows no signs of anything wrong and runs perfect. I'll check it out when i get under the car.

yeah, just bang on the cat and resonator with your fist, if it rattles, then you know what it is. it might be subtle so listen cafefully, because the baffles rattling in mine are super quiet, but you can hear it rattle when you bang it with your fist
