    Anyone else hear the exhaust cutout opening and closing as they press on the throttle? I just noticed this today as I was coming down the street maybe 10-15 mph, as i give it some gas I hear something squeak as if it's opening, then as i let off the throttle it squeaks again... it's like it needs some WD-40 or something.

    Is this really what could be causing the noise? it aligns perfectly to the throttle input.

    Have the car back at the dealer today. The didnt fix it last time I guess they thought it was something with the seal around the headlight intake (miscommunication to the tech I think). I recorded a video and sent it to them so I hope it helps them get to the fix.

    Here's my video of the noise several times throughout.
    Dropbox - Hellcat-squeak-exhaust.mov

    Anything else more specific I can tell them so they get to the root fix quicker (or at all) ?

    I dropped my car off yesterday for this issue. They kept all day and threw it in the shop for 30 minutes. Poured water over the belts thinking the squeak was from there. Today they told me to pick it up they couldn't find the issue. Confused I asked "Did you take it for a test drive?" and they replied "Of course." I pick it up and notice not one additional mile on it so i decided to look at the dash cam. Dash cam ran for 30 minutes from the moment they brought it in till they were finished testing.

    I went back in and said "You didnt test drive it that's why it wasn't found." She asked me how I know if they didn't test drive it and i said "Dash cam". She pulled service manager and he said "yeah we didnt test drive it, we thought it would just happen at idle if it was a problem".

    He threw a tech in the car with me. We replicated it the second we left the lot and they told me they would submit the claim/order parts. Got no paper work for it so i'm calling tomorrow to get an estimate on part delivery. Another user reported they replaced the Cat-Back. Another user reported just the modules. I'm not sure if they are welded in.

    TL;DR - Make sure they take it for a test drive.

    Thanks. This is exactly what I am expecting to happen unfortunately. And yes I am looking forward to seeing my dash cam as well :D
    This is also exactly why i sent them a video 4 days ahead of time but of course they didnt see that until I walked in this morning.

    I'll keep you posted

    Well I got mine back. They couldn't find anything mechanically wrong right now and said they opened a STAR case w/ Chrysler to try and determine the problem.
    I guess it's just a matter of time before enough of us have this issue and until there is a TSB or some other fix for it.

    I'm calling around 1-2PM EST to ask if they have a date or response for the parts yet. I'll post an update around then. I'm assuming they too opened a STAR Case

    By the way, is there a specific STAR case# they found that led them to this decision to replace the cat-back? Other findings or paperwork?
    If I can find out concretely why your dealer is doing that replacement for you I should be able to talk to my dealer and get them on the same page.

    I assume they opened up a STAR Case themselves. The part arrives early next week and I'll see if they can give me the STAR Case or if the paperwork has it. If your dealer runs into a dead end before then let me know and ill stop at my dealer to get the STAR case number.

    What i think your dealer did is they couldn't find anything mechanically wrong except for it squeaking so they just now opened a STAR case regarding it. Chrysler should approve a new exhaust as a response.

    That would be uber annoying, I had several issues with my exhaust valves as well.
