About to get my car on the road for the season soon (Michigan), and I was wondering if anyone has found a lubricant that lasts for squeaking NPP baffles. I have tried a graphite spray lube and a dry spray lubricant, but I can only get a couple weeks before the squeaking begins to return. Due to my car being an auto, I have almost no control over the AFM and NPP operation.

Any info is appreciated if someone here has found a solution. I'm not looking to pull fuses or tune AFM out.

Same here I even put a tray of rat poison out but the darn squeaky rodent never dies! I bought a heavy black grease I'm going to try and apply it with an art type paint brush and see if that works for awhile.

try the white L. spray grease . this is something i've used on every vette i have owned for all the noise inside and out . spray it on move the part around . it last a good while .
but on that d. mode ??? i have that churp or whatever it is haven't had tlme to look .do you think it's comming from the rear D/M or from the from the pipe that is for the back p. for the 4 c. mode , it has a flap too .

Perhaps something like this:

Wow. Never thought there would be a grease type lubricant that would withstand 1200 degrees. Probably would do the trick since it doesn't get that hot back there, and I appreciate the link. I'll have to search around for a similar product sold in a small squeeze tube.

Almost afraid to say it but this thread just made me realize my 2014 Z51 w/NPP that used to have incessant baffle squeak seems to have stopped. I'm currently at 17,820 miles with all systems working as they should. I'm even thinking there are still between 7-10K left on tire wear.

You're right, at the end of the pipes it doesn't get super hot. Another thought might be waterproof grease, if it's moisture that's washing the grease away. Marine grease would probably last a long time if that's the issue.

Yup, or CV grease.

1st I've heard of this "issue"!

Baffle squeak?
Are you serious?
As loud as this motor is, that is hard to imagine...
Turn up the volume on you music or take it to the dealer...

Since your car isn't an auto, your AFM and NPP baffle operation is completely different and far less frequent if even being used at all. The squeak noise happens during the opening and closing of the baffles. I explained in my original post that my car is an auto, and because of that, the AFM and NPP operation is different then a manual.

Can you not go into the options to turn sound management on or off? I just keep my exhaust open the whole time.

AFM is on in all modes with an automatic. The baffles open and shut no matter how "Engine Sound Management" is set.

Oh, thanks for the information. Looks like I'm the dummy
