Cheap Newbee IR thermometer read 340F on input and 141 on output after a while of idle. Anyone want to try this on their own car for baseline? The cat is 20 years old but only 117K miles. Apparently in NY 1995 is the only year where an EPA cat can be installed. Even 93 and 94 require CARB cats or the shop can be fined $26K per cat incorrectly installed. With that - i bet shops will even be afraid to install an EPA cat in my car. I bet the upstaters in watertown NY complained about the CARB cats do it was dropped but ODBCII in 96 brought them back.
