No rattling in mine (not yet anyway) regardless of whether the valves open or closed or anywhere in between.

I have only closed them completely a few times, i mostly leave the valves at 50% open which is a good mix of some noise but not too much for everyday driving.

Thanks!  Also, I sent you a PM in case you haven't seen it yet 🙂

When the valve is closed, does it vibrate/rattle against the exhaust at all the way I've seen some other electric valve exhaust cutouts do?  I couldn't find out whether they have anything to help silence it with a different material or not.
