So which of these do you prefer? And do you have any Dyno post results on the i40 of the before and after? Also, will it affect the every day driving/comfort mode? Is the exhaust flap left open all the time or only while in a certain mode or race? I'm not sure the wife will like the ride if comfort mode with the air suspension is no longer smooth. It'd be nice if the extra stiffness and ponies only kick in while in Sport mode.
