Finally found a company that is selling what is needed for the exhaust valve simulator for the 2024+ 6.2L. Ordered mine the other day and should have it by monday. Will keep everyone posted once I get it installed. Cost $45 for one instead of having to go the other route of buying the pair that fit the C8 as mentioned earlier (which will also work as mentioned by JONNYGMC). Hope this helps everyone in need of this.

Hey there! I installed a Borla ATAK system yesterday and have a CEL, even with the new Borla that's built for the actuator. Did you buy this? Still holding up?

Did you end up putting the ATAK on yet? I just did, and it's the system designed for the valve actuator, I do have a CEL. Going to call Borla on it or just try this ebay clip-in.
