Anyone feel free to correct me if I’m wrong in this, but if you add NPP to a non factory NPP car the valves would just be open all the time right?

Unless... You add your own actuators and wire up your own control circuit to close the valves when you want them closed. |

I don't need the trans cooler or diff cooler. I don't track and my spirited driving will be limited to short bursts. I might wind it up on a empty 2 lane road up northern mich.

More than likely the valves will flutter with the exhaust pulses and rattle like crazy.

Last I checked, springs move under loads. Like bumps or exhaust valve pulses.....

I can follow the logic, but the valves are open. I would think there's more chance of "odd behavior" but not having actuators installed. And if the actuators -are- installed, then the fluttering you're suspecting would seemingly be zero.

The problem you encountered, from what I understand, was on originally installed NPP systems. Correct? And wasn't it addressed by a change to the valves in newer versions of the exhaust? |
