Not as many miles for me yet, but same. Maybe we all have different definitions of “drone.” It’s got more bass sound around 2k but it’s smooth, and zero resonance or weird vibrations or anything like that.
I have the SPD catted downpipes as well. I’m assuming it the combination of the two that results in the dreaded 2k drone.

SPD told me that my 2017 with 54k is considered higher mileage and the OEM mufflers have probably blown out...

what year and how many miles?
2017 34k but not all those miles were with the factory muffler. I did run a Corsa sport muffler for a while. SPD told me that my truck doesn't sound like those on youtube because of a blown muffler. I find that hard to believe. They also stated they were working on their own muffler for the Raptors.

I find that VERY hard to believe you blew out a Ford muffler with such low miles. Everyone with a truck would be getting multiple new mufflers on warranty!
