2012 CLS63 P30
Alright, I just took the resonator off of my 2012 CLS63 (used a custom x-pipe to replace it) and the car sounds very good. Since I just came back from the muffler shop (like 1 hr ago), I haven't given it a few days for the sound to settle. The muffler guy said it would sound a little bit louder in a few days time, as it burns more through the muffler. As it stand right now, the sound is about 15% more than stock. For me, this is perfect because I liked the stock sound, just wished it was a bit louder.
There is no noticeable performance gains, and the car drives the same as before. Obviously, you save some weight by removing the resonator but that's it. There is no problem with the Eco mode, as the car still sounds relatively quiet at idle. It's just compared to before, you can now hear more during 1800-2200rpm acceleration. Before, you wouldn't hear anything until you get over 3000rpm.

I just picked up my first AMG yesterday and I LOVE MY NEW BABY! We are Bonding just perfectly... (Black on Black 2012 CLS63 P30) If I have the resonator will I have any warranty issues? I had a modded C6-Z06 and had to remove the Headers before GM inspector looked at the car which needed a new motor (4,500 miles). I guess most experienced muffler shops could figure this out right?
I highly doubt Mercedes will hassle you for a resonator delete.

All done... the car immediately is louder by at least 25%. Throttle blips yield a very very loud bark. I love the mod and Pepe said that the straight pipes will yield more sound than the x pipe. He said if you wanted more quiet gains then the x pipe is the way to go. And yes the CLS 2012 does not have post cats!
I love the new sound- makes me want to drive the car with the windows down all the time

Thank You for all the replies. We have gotten thru the break in period and are getting along Great! I am gonna make arrangements to take the resonator off. I was a little reluctant and now I feel more confident after the feedback I have received. Ps: haven't had the need to fold down the rear seats but knowing me, if I like the way it sounds I will have just converted my CLS to a two seater! No room for passengers today!!!!! LMAO.

I would love to keep the back seats folded down all the time. The problem is doing that restricts the front seats' backward adjustment past a certain point.

H and X pipes will create back pressure and reduce the over intent of the resonator removal: SOUND... and you wont get more power either.

I'm glad to see this thread being so active and all. The straight pipe set up is definitely louder than the X-pipe on my car. However, I think the DP set up is even louder?!

We were talking about this at cars and coffee yesterday and the general thought was that the res should go back in if you do the catless DPs.

what are the cons of cat less DP with straight pipes?
what about cat less DP with X pipe?
Thanks so much!

I can only guess and judging by how my GTR sounds the answer would be more towards yes in regards to drone. Taking out the cats reduces restriction but also sound baffling too so you will have much more sound and it will be right there under the car. On the GTR I endure it because its that type of car but a Benz is still a luxury mobile so I would fathom that most would not like it as much except for the crazies that want to trap over 130 mph LOL
