If anybody has any ideas please let me know-
I have a 2019 LT, I’m having a pretty bad rattling noise that I cannot figure out. Happens only when the car is warm, starts about 3k RPM’s, nothing loose under the car that I can see, nothing touching, removed the heat shield, that’s wasn’t it. There’s no codes on it. I have a magnaflow competition series CB exhaust, it’s only about a year old but it sounds like it’s coming from more towards the middle of the car so I don’t think it’s that. Was told it could be due to cracked/broken exhaust manifold gasket but that’s look intact as well. Seeing if anybody has any suggestions or has dealt w the same issue before I go shell out a bunch of money to have everything inspected.

 

My awe exhaust rattles around 2k. I need to adjust the driver side where it attaches behind the secondary cat.

Awful clunky rattle resonates through the whole car

Don't think I have enough clearance. May wanna double check, it may not be close when cold
