Default Adjustable Exhaust Silencer?

My 2011 WRX w/ stock exhaust is not the loudest car around, to say the least. But there are times when I'd like the exhaust note to be quieter. I got the idea of making an adjustable "exhaust silencer" from one of the Drive channel videos (the
when the guy goes through the features of the Audi R8 Blackbird).

So, how can I make that happen? I'm imagining some kind of setup that could open and close a valve - maybe a cable operated system that I could control from the driver's seat?

I'm not looking for a permanent solution because about 80% of the time, I enjoy the sound of the exhaust.

Any help would be much appreciated!

on the old cars it was a butterfly in the exhaust that was controlled by vacuum. new stuff like corvettes i think the butterfly is controlled by the computer.

they are called exhaust cutouts. Many options available or you could make one... Not super complicated.
