So hard to judge how much drone is too much for some people. Too much for you like you can't talk inside the car?? Is it painful in the ears drone?
Mine drones but it's only annoying at certain speeds or at a certain idle rpm.
No way around it though, oh she drones.
Maybe some vid inside the car but then again, it's not gonna pick up the deep bass which IS the drone to begin with.

What did you do besides have the Eisenmann mufflers installed? Resonator removal? Secondary cats removal?
The reason I ended up selling my Eisenmann Race exhaust was because even with retaining the secondary cats and the factory resonator, I found the drone between 1,800 - 2,000 rpm really annoying after enduring it for awhile.
It's unlikely your muffler shop messed up. More likely, you're now experiencing the drone of expensive aftermarket mufflers for the first time. They still sound great outside of the car. It's just drinving with the drone that becomes old really fast.

I found the same problem too when I got my Eisenmann race, what I did was asking the muffler shop to add a side resonator to each side. The first photo is just to give the idea of how it will done, and the second one is mine doing the job
The way it does the job is to reduce the low air flow directly to the exhaust during 1500-2000, so after 2000 rpm the flow will be more and thus no drone, the sound will be quiet a bit during low rpm but once after 2000 it still sounds great cus the side resonator are already filled, also it does give you some torque back as well.
