I took some video recently of the exhaust with the valves closed. I have seen many posts about the exhaust so I thought I would film and write my review on the exhaust in closed mode.
I really do not drive with the valves closed, the sound of the exhaust with the valves open is like porn to the ears. Sounds amazing, so I really did not have a good idea of what it sounded like with the valves closed.
Here are the three videos that I took (Had to cut it up because it was a total of 20 minutes)
Valves Closed, Car is cold and revs are under 3k
Valves Closed, Car is warm with power mode off
Valves Closed, Car is warm with power mode on
When many think of a valved exhaust they think when the valves are closed it is really quick. When the valves are open it is really loud. But with the Evolve unit it is a different story. Not only does it sound awesome with it closed, but it sounds really nice compared to many of the other exhausts that I have had and heard. (few days before I drove my buddies E92 equipped with Dinan Mufflers and Challenge Street xpipe, my setup was much louder) There is no drone, none at all when the valves are closed. My girlfriend is now open to driving around in my car because she can have a conversation (blah). She would never get in my car with my old setups, and sometimes with valves open she would get upset lol)
So really yeah you can close the valves on the Evolve unit to be quiet, but it also has plenty of punch for people who want to stay in closed mode and still sound beefy...
