I'd be very upset if a metal gizmo on a road makes me buy a new cat. Sorry.

NOx... Usually increased NOx emissions are cause of too high combustion temperature. I wish I could add that lean mixture can cause NOx increase but I'm not sure on this. Can check it on local site and get back to you later.
