If it's only on the one side, I'd look towards a clogged cat or bad O2 sensor.

Common cause of a cat overheating is a faulty fuel injector dumping too much fuel.

replace the cats, its time anyway and new ones perform better.
replace 02s while youre there if you havent.

Typically an overheating cat is caused by an excessive amount of unburnt fuel getting into it, this could be caused by a stuck fuel injector or a misfire on one or more cylinders. In my experience, the most common cause of a misfire on a Gen1 Viper is faulty plug wires, if a spark plug boot fails, and the spark arks through the boot, causing a misfire.
