Catted dp + EL question

[c63sss]

I currently have stock downpipes, AA EL resonated, and zcp muffler. I have ARM catted downpipes that I will be installing soon but was wondering if I switch to the non-resonated pipes, will there be drone or any sort of bad noise? As someone mentioned in another thread, the resonators make the car sound like it's making noise through a pillow but if there is drone Id rather keep them on. Thank you!

I'd keep the resonated version for a cleaner sound.

In my opinion the non-res version works best with the stock downpipes

id install the ARM downpipes first and see if you like it. if it's still too quiet, then i'd go with the non res midpipe. just beware of the 2k rasp, some people hate it, some people deal with it, etc. you might not get as much rasp though since the downpipes are catted

If using catted DP's, is a single mid with res the best option? DON'T want any drone, nor cel... Not really chain hp #'s, currently have BM3 sag 1 its, and the can ran brilliantly.
Unfortunately had an incident where I ran over a piece of Road debris, and it almost totalled the vehicle. turbo's, whole exhaust (minus muffler) needs replaced.

Would the catted DP and res single mid sound like ass going through the Ti MPE muffler?

Hey I know it's not exactly your question but it may help. Compared to a catless version I have heard, the catted downpipes sound way better. I love my current exhaust setup as I get the volume without the rasp. You may want to try it out. I got mine from Mike and had no issues with Fitment.

I get a little 2k rasp the first 2 minutes in a drive if the car has been sitting and exhaust cold, but nothing when it's warm. Definitely happy with the purchase

Thanks C63.. guessing you did install the ARM catted DP? Not interested in catless, cats and res would be the only scenario I would go.
I'd like to feed it into this :

Been looking at your site for parts for repairing this mess. Waiting to hear from insurance adjuster to see if I can source parts, or if I'm stuck with the dealer quote..

Yea I installed them and I think it sounds great. I actually came from the w205, but you can't beat that 6.2 v8
