Dodge 1500 5.7 Hemi with Flowmaster 40 series Delta - what is the tube for on OEM muffler?

From : aceman

Q: i just had this muffler installed with dual exhaust cat back and it sounds pretty good. however i noticed the original oem muffler had a couple of tubes coming off of it. there is none on the flowmaster. whats that tube for is it a heat riser tube for the carb or is it for an oxygen sensor do i need it hooked up for functionality the reasons im asking is because of a couple of things. i know these new motors are fly-by wire and wondering if it affects functionality because it feels like im losing power during certain use the exhaust smells rich and its droning. did i pick the wrong muffler for this motor maybe i should have gone for the 50 series suv delta should i ask the shop that did it to rig up a tube in the muffler to wherever it hooks up to thanks in advance ace .

are sure your not looking at the mounting brackets geekboy geekisme@geeker.com stated which i commented on below exhaust gasses that have not been broken down by catalyst maybe not sure about that. its a small tube only 1/2. there are two on the muffler and two on the resonator. ace are sure your not looking at the mounting brackets .
