Brandon I meant, if you had put a EGR with no CAT you would get near the same limits as Putting a Cat with no EGR

Cars with functioning EGRS and Failing cats read over 2000 in nox, and once that cat is put on it reads under 400

Same thing with a EGR, if the EGR is failing and has a functioning cat and reads over 2000 once again the nox would come down when cleaning or replacing the EGR

Do you understand what I am trying to say ?
