435 exhaust

My 435 Convertible (Sport Line) has arrived and I think it is great !!
Question: The 335 Convert that I traded in had a great sounding; but not overwhelming exhaust note. The 435 is definitely quiet and luxurious and you can hardly hear the exhaust.
I have been told of a damper of some sort in the pipes that is supposed to open upon acceleration to give it the sporty sound that I want.
Does anybody know anything about this?
Many thanks all.
