Strange Rattle above 2500 rpms??
 

Hey Everyone. So I've been noticing this strange rattle noise for the past few months and it seems to be getting worse. It only happens above 2.5k rpms, never if my foot is off the throttle in neutral, and only after I have been driving for a bit (never when I first start up the car and get going). Everything on my car is stock (unfortunately) and I have no idea what the noise is. I'll attach a link to the noise for you guys to take a look at.

Always go under the car and check the metal plate under the header first. The heat shield on the front pipe/header might be getting loose as well.

I took a look under and noticed a few things on the header were a bit loose but they don't seem loose enough to cause the noise. Do you think so?

Here’s another video of the noise if it helps.https://youtu.be/EZeWPc-Y6TU
