Is there a kit that will allow the stock exhaust to be opened or closed at will?

Diode Dynamics

There are plenty of good aftermarket options with valves you con control volume with.

*PPE - also a forum sponsor, has a dual-mode exhaust for the RCF

Armytrix is another option, they have some good videos out there on YouTube.

I just cut off the resonators and put straight pipes, the sound is decent under load, and quiet when cruising, no drone.. works for me. $80 and done.

QTP (http://www.quicktimeperformance.com/QTEC/) has kit that opens and closes the exhaust that could be mounted technically anywhere in the exhaust piping. It pretty much becomes an open exhaust.
You could install this closer to the muffler so it is not obnoxiously loud which most companies like GTHaus and Armytrix do.

Now that I think about it, that's pretty much what they do on their exhaust system but charge you $4000. And I believe one of them uses QTP kit as well.
