Although no permanent solution was ever really found, I noticed even my 2023 LT1 with NPP start doing this when I switched the modes randomly around 15k miles, and now at 22k miles it squeaks all the time; when I switch modes and as it opens/closes depending on throttle.
Pulling the fuse is cool and all at times, but gets annoying over time for a few different reasons.
Even though I feel bad that many of us are experiencing this with our sweet baby’s, this thread with frequent updates has been one of the funniest [and still helpful] that I’ve seen on here yet… 😂😂 I do appreciate your tips and outcomes of the potential fixes for this, though. Pretty dope GM is cool enough to replace the whole exhaust if the severity is taken that far!
