This.
These videos do no do either exhaust justice. I'd say the quality is sub par in both cases.
Not to mention, nobody here really knows exactly how NPP works when just revving. We know that on the 5th gen, the valves work on vacuum and are open at idle and in park. But on the 6th gen they are controlled electronically, but we don't know if they are always full open while sitting still in idle/park or if the mode the car is set to changes the sound like it would going down the road. So do we just assume the car with NPP was full open? I don't know about that.
Anyways, I can't imagine for the life of me that Chevrolet would make the NPP more tame, in full out track mode than the standard SS exhaust. Track mode, and maybe even sport mode, should put the exhaust at fully open, but I can definitely see that normal mode may be quieter than the standard SS exhaust.
For me, I love how NPP sounds on the 5th gen, and on the C7. I'd be pretty surprised that I wouldn't also like NPP on the 6th gen. With cats, or LT headers, I think its as aggressive as I'd ever want. For that, and b/c I really like the tunability, I'm going NPP.
