I have a base V6. I was pulling up to the valet when a V6S was just about to leave and I think it sounded louder and meaner than my car on startup. Anyone know this for a fact? I didn't test drive a V6S. My base V6 has the active exhaust... I was hoping it would sound exactly like the V6S.

 

The V6 S is slightly louder than the base V6. It's also possible that the other driver had left his car in dynamic mode when it was parked. Dynamic mode will remain active for 6 hours unless you manually shut it off. Startups when the car is in dynamic mode are louder because the exhaust valves remain open.

 

Yep, definitely louder in Dynamic when you start up.
