His logic behind it is the second cat. and resonator NEED to be on there to create enough back pressure for the engine. Can anyone give me some insight or input about this please
#1, your co-worker is wrong, it will not ruin your engine at all.
#2, your CEL will not go on at all unless a sensor has been fudged with at all, but no sensors even get touched in the process
#3 do it
you will not regret it, it will help pep up the engine even more
