See, but the "bolt up" is not the real issue. The issue is whether or not an LEV cat is "compatible" with my ULEV Accord!
I'm told by the Honda techs that it is not. Something about the ECU won't read right and won't know how much fuel to add or something because there is no O2 sensor on the LEV cats (I'm fudging here, but you the idea).
Emissions is a concern, yes.....because Maryland checks emissions here. My car is daily driven.
So with that "light" are there any other less expensive, and doable fixes?
