2018 stock m240 midpipe

Any pics of the stock midpipe on the 2018?
I know they deleted a section or changed it a bit.

I have a 2018 M240i and the midpipe still has two resonators as in past years. I can't tell if the internals of either resonator was re-engineered, but the sound was still too quiet for my taste. I deleted the rear resonator. My exhaust guy assured me that because of the larger volume of the rear resonator, deleting it would increase the sound more than just deleting the front resonator. I took his word. The result is more sound and more distinct over-run burbles, but not overly loud. This was a compromise from deleting both resonators since my wife is not fond of louder exhaust sound.

Interesting and good to hear as others I've read say removing the front resonator will produce more noise compared to the rear. Cheers
