No, the exhaust baffles are not computer controlled or anything. Those butterfly valves are only opened when there is enough exhaust pressure (ie. RPMs).

On the other hand, you can either cut them out or simply wire them open if you have the Range AFM disabler installed, as they are designed to reduce the coffee grinder noise you get when the L99 engine goes into 4 cylinder mode.
