I have a resonator same vibrant everyone uses. I’m much more sensitive to drone I’m sure also... and my rear section with the Y splitting into dual mufflers design could add to it. As well as my exhaust tips not protruding far past the bumper, lots of factory could be at play.
I also plan to fab up a Helmholtz 1/4 wave at some point as well.
The idea of “no” drone is subjective... if you run as frequency analyzer in the car I’m sure it will pickup and resonance peak and frequency range.
You probably losing your hearing some, lol cause if I recall you don’t even have a muffler in the back and you still don’t find it loud, lol.
My car being catless now / with the res. / and dual mufflers is a “very loud 4 banger” for me
