Correct, these are basically pipes but what's interesting is that this exhaust is only somewhat louder than my past Meisterschaft GT exhaust I had on my 135i which did include a muffler. Maybe there was little baffling?
The current OEM muffler on the 1M is pretty hollow as well. It doesn't sound like there's much baffling here either.
