Is this an exhaust leak? Something else? HELP

I'm not talking about the constant ticking noise, I'm talking about the rattling noise that is slightly noticeable in the background.

Yeah that sounds like the DPs are rattling off something for sure...Could be the heat shield near the front turbo hitting the heatshield or even the OEM brace that held the OEM dps....What I was told was before reinstalling my AR dps bend that brace or even take it out to prevent it from hitting the 3 inch pipes and..Also make sure the DPs are not touching each other....
What brand of DP do you have installed?

Macht Schnell. Have had them on for about a month now I think, noise started about 3-4 days ago.

I listened to it about 4 times and it sounds like the DPs shifted a little and maybe hitting something since you didn't hear this noise before.....Doesn't sound like exhaust leak IMO...I would get under there and look at it....

Well if thats the case it maybe a leak but I doubt it and still think it is hitting something and causing this slight vibration kind of noise, but then again a pregnant women, they sensory glands are magnified when they are pregnant...Their sense of smell, taste, hearing, emotions are all amplified so you can't use your wife complaints, because they all complain about everything and anything when their pregnant!!!
