I need help identifying what parts I need. All information online is for Yukon xl 1500 or other that do not match my 2004 Yukon xl 2500. After a trip into the mountains I got code p0449 and upon looking around I noticed something that appears to be mounted in the rear right behind back bumper area is completely missing. I have two hoses and wiring (two wires) hanging loose. Auto parts stores have been no help, telling me I need the part that goes up on the engine or other misinformation. Please see images and advise which part appears to be missing.
The smaller hose is the one I can find no information about. It was quite loud like the exhaust pipe and I placed the blue tape on the end just for vacuum purposes.
