Does the left exhasut flap ever open at all in my M235i?
Just wanted to ask whether it's normal that - in those modes where the exhaust left pipe flap should be opened (DSC off, Sport+) - the right exhaust is still noticeably louder? In fact, I switched the modes and listened carefully to the pipes, but it's still the right one that emits the low-note burble; nothing similar is ever audible with the left pipe...
It's possible that the flap system - even when opened - changes the character of exhaust note so that the left pipe will never be as loud as the right one, but I 'd like to know for sure as it's also possible the Service did sth wrong when installing the MP tails with intermediate pipes lately.
