Dennis, I wanted to be sure you read my whole reply...
Our church's play yard... Broken "spout" made it "unplayable" and it turned out that sourcing a whale, ordering a whale, shipping a whale, finding it's installed with "security" fasteners turned this simple project into one that's run all summer.
I looked under our 2002 and it seems the cat looks like this one
but there were other styles on RockAuto.com where I got this pic. Clamped on the front/inlet end, welded on the rear/outlet end. Other styles have a flange on the inlet. You'd have to match it up, make one, maybe two cuts, and clamp one or both ends.
But I think what you'll find is a loose heat shield.
