I think you will get a cat efficency error? BTW you don't necessarily need flash for straight pipes. a spacer on the secondary cats will do the job just fine!

If your tune doesn't have cat function deactivated, you should simply see both banks cat efficiency codes, nothing else. mixture too rich codes are triggered by other faults, not a lack of cats
