If you keep your cats and just add the short tails it should have a good note and not to overbearing loud. I’m actually considering removing the test pipes and adding cats back in on the supercharged car
So aside from buzzing/rattles, I really like the sound. Considering you've done some heavy mods to your vehicles I want to get your professional opinion. Alot of people say that removing the mufflers will create a loss of back pressure, hence loss of performance/low end torque. Im just curious if the ECU will compensate for the muffler delete? No plans for a tune probably until the warranty is up.

EDIT: Also I have the torque app with OBD II connector..not sure if you are familiar with that. What should I monitor after installing to make sure everything is running correctly?
