I was watching Top Gear and they were showing the new Jaguar F-type which has a V6 engine and it sounds brutally amazing.
It has a valve inside the muffler (just like BMW turbos do) that opens up under certain exhaust pressure, so basically you get a quiet, drone-free cruise, but turns into a beast when you push it.
On top of that, the Jag has a "sport exhaust" button, that manually activates said valve so you can keep it open permanently. Awesome.

That go me thinking - I know that Dynomax makes the VT series muffler, which includes a spring loaded mechanical valve. Has anyone thought about making that electric, for push-button control?
I know electric cutouts exist but I want something more sophisticated, not just a brutal hole in the exhaust pipe.

Also, in general, what do you guys think of the Dynomax VT sound? (I have a V6.)

 

My neighbor bought mine, so I will ask how it sounds. She has a 2014 V6.

 

I haven't heard it yet first hand, and listining to You-Tube vids just don't do sound justice.

 

I stoped by the neighbors to hear the exhaust and they sound great. One point they are not loud so He is doing the resonator delete.
