hey, i am researching some stuff related to getting late model Supras.
is the j-spec cats a 3-way regulated catalytic converters?
are they the same on US, EU or UK specs?
are they same for all years (1993 to 2002)?
according to the manual for a 1997 US-spec, both cats is 3-way in US-specs.
i am assuming they are 3-way, but assuming is different from knowing![]()
