Custom Electric Exhaust Actuator

Has anyone ever installed an electronic exhaust actuator on a Z3 2.8? I fabricated one up to cut in post cat. It will give the rear a quad exhaust look all wired to a switch. I set mine up for 3 settings: fully muffled, half open, and post cat straight pipe. I used an actuator from a retired XM1 tank for cannon pitch. I was just going to go with two settings but i didn't have the software to reprogram it. I'm wondering if I flip the switch to post cat straight pipe if the CEL light would come on? I plan on cutting in the Y about one foot behind the post cat O2 sensor. I know you guys are Z3 enthusiast, so what do you think? This is only for sound no hp gains.
