and Brandon only a difference of 600 eh, A lot of cars that need a Cat fail at the same reading, and once that cat is on it is usually under 400 NOX, but that was not the case with your mr2, If I recall did it come with a EGR ? I dont think so but im not sure, If you had put the EGR first and tested it with no cat, I Garuntee you would've got the same Readings


How would I get the same ratings if I installed a system that is put in place to reduce NOx limits. The USDM MR2 with an EGR valve passes those limits no problem. Only difference, engine wise, between jdm and usdm, is the EGR valve.

And yes only 600, because a 3 way cat is not something that can drop the NOx limits like an EGR system does, that is what it's there for.

I went over this with Durham Auto Works, Can-Saf, Tomlin, Yoshio, and my family mechanic.

And the cars might be different, but all EGR systems work the same.
