Weird Metallic Sound

[MustangGuy23]

Hello all,

This is my first post on the forums!

I have a 2015 Gt and it has 78k miles on it, I recently had kooks long tube headers installed with cats, they connected it into corsas through an oem connection because the aftermarket connect wasn’t long enough. When I got it back I’m 90% sure it started making a weird metallic sound and I am concerned about it, does anyone have any idea what could be making this sound?

(If the video didn't post I’ll try to post the video again, Internet is not the best sorry)

Sounds like a loose clamp/coupler - also a possibility that they moved some of the heat shielding around and its now lose as well.

Doesn't sound like anything detrimental at all - just something loose.
