I bang my hand on the passenger side convertor and recreate the noise.
Seems like the 'guts' have crumbled and are rattling in there - sounds alot like a rod knock.
This assembly includes 'y' pipe and 2 convertors.
Dealer price $550 plus $40 core plus $35 in gaskets!!
Plus $150 install.

Are you sure it is not covered under warranty? I don't have my Yukon today with me to check the owner's manual; however, the cat is covered by the emissions warranty which is longer than the bumper to bumper 3 year warranty.
