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.
Please note that aftermarket catalytic converters are not
legal for installation in California on OBD II vehicles (some 1994 & 1995, and
all 1996 and later vehicles).
