Default Hissing noise proflo exhaust

Is there anyway of stopping the hissing sound on a duramax at idle so it just has the nice v8 burble

I thought it was the turbo but its a very loud hiss it stops for about ten seconds every now and then at idle. It almost sounds like an exhaust brake is stuck on

Hissing sound indicates a crack in the exhaust manifold, exhaust pipe or a leaking gasket. A chugging noise could mean a blockage in the exhaust system.
