I was wanting to find out more about any early adopters of the aftermarkets exhausts. The M235i appears to have a very insulated cabin (much more so than the E92 I drove previously) Because of the very insulated cabin I am more apt to go with a more aggressive exhaust and I am thinking drone may be less of a problem than previous models. I have found little videos from companies and users with in cabin video and user experience.

Aftermarket Exhausts:
Castro Motor Sports
Supersprint
Manhart
Meistershaft(future)
Challenge USA (future)

Question

1 - How would you describe the sound of your aftermarket exhaust and can you provide videos in-cabin and outside?

Personally I am looking for a more baritone with enough of a sonorous finish to the exhaust sound and found the Manhart and Meistershaft the most to my liking from videos.
