Exhaust fumes on 2017 Challenger 550

[markus]

I have a 2018 challenger with 35 hours. My exhaust pipe came off.  One stud is missing and both nuts, There is a plate  that holds pipe onto the exhaust port. what does the gasket (donut) look like? I found a small round gasket. It fits into the exhaust port then the pipe then the plate then the nuts hold it all together. Is this right? I have no schematics to go by ?

J did you figure out the exhaust problem?

On the lower right side of engine (passenger side) the 2 1/2 rubber outlet hose your talking about is cooling fan from engine.  You can extend that a bit down and to back and will make a little quieter.
