Hi, just ordered a 2021 GT/CS with 400A instrument cluster and active valve exhaust. Can the exhaust be programmed to start in quiet mode during certain hours….like 6am to 8am?
Or is that only available with 401A?
thanks
Bob

Yes - at least in 2018 400A car it could. Pretty sure that hasn't changed.

Yup! It’s the last option in exhaust mode selection called Set Quiet Start. It’s definitely worth it if you like your neighbors haha

What, you didn't read all of the 492 page owner's manual? ;) My 2019 400A is set to always start in quiet mode (stays there until I leave the neighborhood).
