The Mexican mechanic I referenced earlier dropped the piping, cut a larger rectangle out of the top of the converter, beat the innards out of it, and welded the top back on, and put the pipes back.
And no, the set up the Mexican mechanic saw on the Bravada looked like a normal, everyday converter... bolted on.
Guess your 02 is gonna look like one of these.
