Looking to buy 2 Exhaust actuators (gm# 22839592) for NPP exhaust.

OH THREE Z

Im putting a set of Corsas on this weekend so i wont be needing my actuators. 2015 Z06 with 9000 miles. Only in rain a couple of times. If interested shhot me an offer.

How does $100 each sound and I'll pay shipping. Seems to be the going price. Someone sold a par recently for that.

OH THREE Z

Im okay with that. My goal is to have the Corsas on Saturday. As long as that goes as planned and i am happy with the sound they are yours. If you find someone in the meantime that has a set ready to ship to you it wont bother me a bit if you grab them.

Ill PM you this weekend to give you an update

your Corsas will need the actuators .

OH THREE Z

Why will they need the actuators?? I know that the extremes do not retain the functionaity of the bi-mode NPP and i was under the assumption that the harness (or whatever plugs into the actuator) is zip tied and that is the end of the story.

I have a set still on the mufflers I removed. If it doesn't work out I will sell for $220 shipped. They are just sitting in my shop. Had 3-4K on car when removed.

All C7 mufflers has 2 actuators & has something to do with the DOD If you do not plug in to the actuators you will get a dash light & have codes that will not go away & you can not delete them. my tuner tried with AP tuner with no luck .

In photos of the C7 Z06 mufflers, there is not an AFM valve ahead of the mufflers and thus no actuators. Is this correct? If so, then if you're not switching exhaust mode with aftermarket mufflers you don't need actuators.

The C7 z06 does not have the entrance actuators but they do have the exit actuators & are controlled by the ECU & the same goes for the C7 which has 2 & Z51 has 4. If you installed a aftermarket mufflers that does not come with previsions for the actuators you will need to find a way to hook them up.

Complete. Actuators have been purchased. Thanks for all the replies.
