The exhaust solenoid may react the same in Comfort vs Sport, but the burble on throttle lift off is noticeably more prominent in Sport/Sport+ than it is in Comfort. That's due to fuel injection rather than the exhaust system though. Aside from the burbling, the exhaust sounds the same to me in all modes.

It may also depend on the trim level. My car is a 35i.
