so removing part of the cat will throw a code because the rear 02 will think the cat is damaged
Not sure how you are going to remove just part of the cat either without tearing the whole thing up...and for little to zero gain. Just get test pipes and a tune

The stock cat has a separate 2nd cell AFTER the rear o2 sensor that is not monitored. That's what I am questioning to remove...if it was monitored it would have 3 sensors per back if that makes sense..
