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.

I'm really looking to get rid of the secondary cats..
