Borrowed this picture:
You can see the actuator attached to the left side tailpipe (driver's side) in that image. |

It is rev-dependent. Low revs = closed. High revs = open for proper exhaust flow.

Also, it's closed when the engine is cold. It only starts to open up when the engine warms up. It'll also open on idle or at low rpms. Just drive slowly through a parking garage to enjoy the pops and cracks from that left pipe!
