I am seeing most high flow cats do not require the air tube when shopping to replace my 1981 Corvette CAT. Can the AIR line at the stock converter be capped off safely?

Not if you need the emissions control system to work properly.

There are high flow cats out there that you can still hook up the air tube. Magnaflow installed mine...
