The power difference is 6hp which I wouldn't notice. I have them open most of the time and I never got annoyed or had issues talking with someone or listening to the radio. It just feels healthy and right with them open.

I've had them on my 09, now my 013, both convertibles, wouldn't have anything else, no drone at all, closed or open. Run them open 99.5% of the time.

It's a great system. Get the Mild to Wild switch and you have quiet or loud when you want. Those that say they don't drone when open don't know what drone is. They drone when open. Get it!
