Does anyone's 6.4L Hemi NOT have the infamous chirping noise?

Or should I expect when mine arrives from the factory in the sky sometime in Jan that it will have it too?
 
i have the chirp on my 2020 done it since new and 16500miles now and every single one I have heard does it. I have owners say theirs does not do it but as soon as they start them I hear it. Every one on the lot did it when I bought mine. I do not have lifter tick but that stupid chirp.
 
No chirp, but I do have the same noise as Crusty old shellback. Not sure if that’s the “chirp” people talk about, or if that’s something different, I’ve never actually heard what the “chirp” sounds like.

Well, I'll just expect it on mine too then.

I hear mine occasionally while driving. I swear it sounds like an exhaust leak sometimes.

I had a 2019 5.7L and upon start up it sounded like an exhaust manifold leaking as loud as the ticking was. I hated it. I love the growl of the 6.7L now...
 
No chirp here. Lifter noise until it warms up. Exhaust leak noise after that
 
Noises that yes, likely won't affect the operation of the vehicle but do make it sound less than par as far as quality on a $50+k truck.

Mine does the chirp. It's annoying. I have disclosed it to all that I think would appreciate knowing that my new truck sounds like a turd so I am kind of over it. This lifter tick may worry me if I had that.

Ok, so if the exhaust tick is the chirp, then yes mine has it, until it warms up.
I know some had a chirp and it was the belt, so thought that was what people were talking about.
Maybe if we call it the exhaust chirp, it would not confuse people.

As for the chirp itself, I talked to my exhaust guy about it and if it could be fixed.
He didnt have any ideas on how to fix it. Seems like a bad design/manufacture of the 2 to 1 merge pipe off the cats. Once it heats up, it seals off completely and the chirp goes away. Seems to be coming from where the 2 pipes are formed into a oval and slid into a single round pipe. Maybe not a complete weld between the 2 pipes.

I would think if it was some type of weld issue it would slowly go away as it warmed up, sounds like a switch gets flipped (not literally) when it warms up it just stops. Kind of makes me wonder if there is some type of back pressure valve that is supposed to help the engine warm up that opens at a certain temperature…
