Excellent concept & execution. My only concern is that the "open pipe" (premuffler only) will be too loud. I've been in a 3.2 running only a premuffler is it was a problem at higher RPMs & highway speeds - that is, it attracted unwanted attention from the rozzers (you know, those folks who "protect & serve").

Do you have dB values for open/closed?

That being said, I still love the active exhaust concept for our older cars. In fact, I was trying to block the second pipe in my 1-in-2-out using an active valve and my efforts were wonky at best. I didn't think of doing it back at the premuffler.
