I only ask because when I called my local BMW parts shop to ask about purchasing the 'IS muffler for my 2010 335i coupe they told me the exhaust flap system worked differently on 'IS models and thus it would not work correctly on my model.
So it worked correctly for you?
It definitely fits because I had it on my 08' 335i
The exhaust flaps all work the same way on 335i's.
