I mean, technically it's still a pre-production vehicle, so is it possible Nissan may take into consideration everyone's feedback on this front and find a way to liven it up?Needs down pipes and a catback exhaust direly.
I have the same on my Q50. It's as you describe. Vocal, but not obnoxiously so. I had a FX45 before that which had a nice deep note to it. I missed that when bought the Q.I think the exhaust sounds good, I like quiet exhausts. But, I'm getting older!
I'm sure Nissan will offer an OEM upgrade for it, I have the OEM "Infiniti Sports Exhaust" on my Q60 (VQ37 version) and it is very vocal, borderline as loud as any reputable aftermarket exhaust.
