Anyone running catless DP's and CP-E midpipe with stock muffler?

Just curious to see if anyone is running this setup cause im trying to keep my exhaust as quiet as possible, but also getting rid of all the cats..
I currently have on catless downpipes, and thinking about adding CP-E midpipe w/ the added resonators...
any opinions on this setup

+1 this is the setup I am going for, I know that w/o the resonators it has some annoying drone to it.

CP-E makes excellent products... you shouldn't be disappointed.
The stock catback is a 10+ hp bottleneck when pushing the car though.

Just running catless downpipes with stock midpipe and aftermarket muffler

Downpipes allowed the turbo to spool up quicker, not much more noisier.

I have catless DP's and CP-E axle back and it sounds nice but the drone is too much.
