Group Buy For C63 Down Pipes with and without 200 Cell Catalytic Converters




I have a question...
I have 2017 C63s coupe with the performance exhaust and I had the secondary cats deleted....
My question would be, if installed these dp's with 200 cell cats, would there be much of a difference of what my car sounds like now and performance gains, if any ?
Thanks

Any feedback from you guys running factory performance exhaust and no cats? Does it still get pretty quiet in quiet mode? Nice and loud when open? How's the smell? Overwhelming? Or subtle?
