Cold Start Weird Exhaust Note
I bought my 2018 C63S brand new and noticed recently a change in the exhaust note. On cold days, cold start, when I decelerate in Race Mode. It starts to make a "gurgle" sound at lower RPMs. My C is not modded at all. This sound reminds me of that one exhaust mod that makes way more pops and gurgle like sounds all throughout the RPMs. I also have the issue with the rattle that I read about on here, just need to get it in to get it fixed.

Start your car, take a video with your phone of the noise and upload it for us in that thread. We'll check it out.

If its an exhaust rattle, you can take it to the dealer and have them replace the part with the butterfly flap. They replaced mine and it took care of the rattle. If you did a secondary cat delete, just mention it and be honest. They will most likely look the other way like my dealer did.
