The Nissan Path

rap633

I am new to this board, however, I am not new to wrenching. I can't put 4 cats on a vehicle that only takes 2. For part of the manufacturing year labeled 2001 the Pathfinder had a manifold cat as well as a downstream cat on each exhaust. I have listed the part#s from Eastern Catalytic. LR 6755-05033...

I bought a 2001 4wd. I live in Colorado and had to pass an emissions test. It passes easily on everything but Nox. The NO level is over twice the limit.
Has anyone here run into this, and do you have any suggestions.

I have already done basic tune up and changed all 4 Cats!!!!!!!!!!!!!!
