I am also tuned, and so M-engineering has even greater power gains from a completely valveless system per their data.

During normal driving valved is very close to the silenced (non valved) centre however once you get into throttle and the valves open on the valved system its louder than the (non valved) silenced centre
The non silenced non valved system is the loudest under all conditions

I realize now that doesn't necessarily mean it's the quietest overall, just that perhaps it is more civilized when cruising in the lower RPM range when the valves are closed? Is that correct?

Thanks guys. Jonny, I went back to my emails and what you actually said was the valved system would deliver "the most drone free experience" of the 3 options, when combined with the stock cats.

I’m interested in the JCR Valved Non-Silenced center. I really don’t want to tune (CEL) or get a valve controller, so from what I understand, I won’t need either if I keep the stock cats. Is this correct?
It seems as though, without the valve controller, I would just use the normal dial to switch between:
Normal: Valved
Sport/Sport+: Open
Is there any other difference between Sport and Sport+ with this exhaust?

In Sport/Sport+ the valves aren't fully open either. They keep actuating to be partially open but never fully. You have to get a tune or valve controller for full open/max sound.
The only difference in Sport is like any other exhaust; you'll get the pops and burbles, whereas in Sport+ you won't.

Stay tuned. There should be multiple JCR exhaust reviews popping up on here in the next 90-120 days when the group buy exhausts are shipped.
