my 02 don't have a Cadillac Converter either.
What transmission did they have?Neither my 99 nor my 00 had catalytic converters. Perhaps the gas engines did?
My 96 had a flattened pipe and cat, now my shed has the cat. and flattened pipe!the 94 to 97 powerstroke did indeed have a "flattened" downpipe to help with firewall clearance.
with very minor firewall massaging a 3 inch downpipe will bolt rite up.
