That sounded like the valve was open.
If it has NPP, it will be much quieter when the valves are closed. Kind of like having the best of both worlds. Quiet when cruising and open when you want to raise some heck, not to mention that on the Vette's, it's worth 6 extra horses! 
Nice find on the vid too! Thanks for sharing! |
Yes it does. It's the same system on the Corvettes.
