I went as far as reinstalling the thing since I thought I had a leak.
I have had catback exhausts on many cars before and oddly enough this car has the most drone.
Since it is near impossible to install a resonator anywhere in this exhaust, I am thinking about cutting my factory exhaust to retain those secondary cats and mate it up to the UR exhaust.

I only purchased the rear section of the UR exhaust because I had a feeling that the drone would be pretty bad. I'm going to use the stock resonator and possibly delete the cats later.
IMO, the drone will disapear with a resonator.
It's getting installed today, and I'll take some pics
