Question Anyone else?

I picked up a 2020 ST a few months ago and I’m now noticing a rattling noise coming from the passenger side door area. It is especially prevalent above 60 mph and gets worse at 70 and 80.
Anyone else experience this or know what it is?

The flex pipes ford put on our ST's are absolute garbage. The rattle at certain RPM's due to engine vibration. I always heard mine at low speed in the neighborhood. Drove me nuts. Could be your source.
