I have the exact same noise! Does yours go away as the car warms up? I brought mine in and the dealer found an exhaust leak from the gasket between the down pipe and the mid pipe. They did the work, and it got better, but it is not 100% gone. So I think they did not replace both gaskets that were required.

I‘ve seen that thread but never heard the noise which it would do.
But do you really think an 06/20 built would have the problem which is existing since 2015? |

So I am still dealing with this, cannot figure it out. Still think it is some type of exhaust leak. I had the gasket replaced by the dealer, and it was different, but then came back. So IDK. Probably just need to do the replacement myself to know for sure. Would love to hear if anyone else figured this out.

Issue resolved
Turns out it was an exhaust leak, more specifically a cracked downpipe. I was using the ARM catless dp at the time so quality could be questionable but I replaced them with AA dp

It turned out to be a crack in the flex joint.

I'm having the exact same sound except im on stock DPs. Ugh I can hear it driving next to a wall so it's hard to pinpoint exactly where the sound is coming from.
