2020 TB Exhaust Leak?

[ZimmTruck]

Hello... Just moved from a 2017 5.3 LTZ to a 2020 6.2 Trail boss... Truck is awesome!

 

I noticed a "whooshing" noise from below the passenger seat under light acceleration. It sounds like an exhaust leak? When starting cold it sounds like a leak, and drips water at the exhaust joint under the passenger seat, I think it is a flex joint? I am mechanically adept, and was thinking about taking it apart myself, but figured it is a new truck should let the dealer take a look...

 

I took it to the dealer today and they asked me to bring it back once it has 500 miles on it, I am close, so probably next week.

 

Anyone have noise like that? Is that normal and I am just not used to the sound?

 

Thanks!!!

Have you found anything out about this? I was wondering the same thing.
