Valves closed, no drone at any time. For me, it's exactly what I was looking for. The power tap is not difficult if you have a shop that knows these cars. I opted for the remote control and my shop tapped the cig lighter in the trunk for power. Ive had no issues.
Thanks. This is now confirmed by two people on the board...and better aligns with what I am looking for in an aftermarket exhaust.
