95 zj cat

Just to be clear about removal of a catalytic converter.you should not remove your cat due to emissions,i was just wondering from a performance side of things if i was using it for off road purposes only if it would hurt the engine not to have one..there are plenty of off road jeeps with and without one.i was wondering the pros or cons from a performance stand point only..sorry for confusion..
