Under Federal EPA regulation, replacement of original catalytic converters
is allowed only if the original converter(s) is missing, or the vehicle
has more than 50,000 miles or is at least five years old and the need
for a replacement has been established and documented, or a local inspection
program has determined the existing converter is in need of replacement.
