    Hello,
    I'm just wondering If It's normal that exhaust sound become very loud and aggressive after 30 min of high speed trip? And It change back to normal ?
    Thanks

    The car's ECU actually has two modes in each of Sport and Race (this is independent of the manettino setting). If you are accelerating or cornering hard, the ECU will cause the transmission to shift more aggressively (particularly noticeable on downshifts under braking) and open the exhaust valves earlier so it will sound louder. It will revert to "normal" when you drive less aggressively.
