Corsa Npp Squeaking
Hello, I've recently installed Corsas Npp Option on my Z06. (14777) I'm hearing an occasional squeaking/chirping noise while in 5th gear. I believe I'm hearing the Npp valves open and close while in 5th. Has anyone ever had or heard of this issue, or know of a fix? Thanks, Ethan

I have a 2021 lte and when I bought it I was making same noise after a week. I took it in to the dealership and they said metal on the exhaust was rubbing making that noise. The ended up replacing the whole exhaust https://19216801.onl/ https://routerlogin.uno/ .

Same issue when I switched to the borla atak. After taking to dealer and “relearning” values still same issue. New system was sent out.
Upon installing the new system found the issue, the first installer reused a ripped gasket on the passenger side. So now I hand them new gaskets and check after install. (3 times now)
I’ve now switched Coupe to HTC and reused system, each time new gaskets and no issues. Z51 system btw
