I got my secondary cats and resonators deleted and got them straight piped. It makes the car sound like the the sound generator is active all throughout the rev band. It also sounds a lot throatier after 3k RPM. I am running stock mufflers until my Joe Z comes.
In essence what you hear inside the car is what is heard outside the car. No perceived drone as the stock setup drones a bit already.
After the first day there was no support welded in between the pipes in the mid section and it caused the pipes to rattle and vibrate. Once the exhaust sorted itself out it (welded a support beam and natural expansion and cooling), it actually sounds pretty good with some rasp above 5k. When cruising the exhaust is near silent and could pass as stock. You get the best of both worlds.
I think when my Joe Z axle back gets it'll sound pretty good.

I've heard from a few people that got their muffler delete like the sound of it and are pleased with it. :-) Probably getting mine done, let me know how it is if you do it!

What about replacing the secondary cats with hi-flow cats and resonators? Maybe the cat is the one canceling most of the sound if deleting the resonators did nothing.

Do you have an exhaust layout on which the secondary cat/resonator is?
Maybe the shop I went to did it wrong. Basically my shop removed the thing before the axle back system.
So with the secondary cat and resonator removal how much louder compared to stock on the exhaust note?(stock sounds super quiet and boring)
Can you post some sound clips in different RPM bands?

I'm not even sure if its the resonator, what specs are you talking about? I'll take some pics to show you guys.
I think some rasp is okay. So far i have yet to hear a decent sounding exhaust for this car.
