Just where does it say that the manufacturer has to replace the
cat at failure? I need to find that asap. Directions to that in
the warranty?
Marc Wiese, 2 1994 RX7 FDs
It does not say that in the stuff they sent me. As I recall it
is an EPA or CARB requirement but I could be wrong.
It may only be in California and there is a mileage or time limit.

Everything you ever wanted to know about EPA mandated warranty (and
then some):
...for the first 2 years or 24,000 miles, whichever comes first, the
manufacturer must pay for all repairs necessary to pass the emissions
test and...
...for the first 5 years or 50,000 miles (8 years or 80,000 miles for
1995 and newer vehicles), the manufacturer must pay for all repairs to
primary emission control parts (only the catalytic converter, the
electronic Control Unit and the On-board Diagnostic Device for
1995
and newer vehicles) which are necessary to pass the emissions test
(1995 and newer vehicles have slightly different warranty coverage
time/mileage/parts limitations.
Emissions control warranties protect you, the vehicle owner, from
the cost of repairs for some emission related failures that are beyond
your control. Manufacturers are required by Federal law to
provide
broad emission warranty coverage for vehicles that are less than 5
years old and have been operated for less than 50,000 miles (8
years/80,000 miles for 1995 and newer vehicles). As a resident of an
area with an Inspection/Maintenance program that meets Federal
guidelines, you may be eligible for a special form of the protection
called the Emissions Performance Warranty.
