Don't know if you guys noticed, but the car in the first video is definitely a manual!
Honestly, stop moaning about the exhaust. This is louder than any standard 335i.
Either way, exhausts can always be changed. Most of us always go for aftermarket either way. I'm mostly interested in the feel of the car. Will it feel raw, fast and agile, or calm and muted like the new M5. The old M3 gained plenty of weight and lost that old, raw charm of the E46 M3. I'm hoping BMW will be bringing some of that back, having learnt by the 1-Series M Coupé - which was a fantastic little car.
