Other than the noise, the truck runs great.
Well did they tell you the pipes were leaking or did you tell them to replace them?
If they said they needed to be replaced and there's still a noise they shouldn't of returned the truck to you as at the dealership as this would of failed QT.
Also they could of left a bolt loose or broke a bolt from manifold or up-pipe or even turbos.
Call service manager and ask if they did a QT on your vehicle.
Also give them a chance to resolve the issue and ask them to approve any charges.
If not leaking could just be loose turbo boot.
I had my bed pan replaced and was in shock seeing my truck all taken apart. View my albums. I was lime holy cow hooves.. Lol..
Relax as you are not at least having engine codes..
Also check for black marks around all the silver insulation on the cab that behide the turbos for leaks.
Have someone rev the motor a little and you look around for the hiss.
Keep us posted
