Hello,

Long time lurker here...

I have a '98 HX with a cracked exhaust manifold (manifold with the integrated cat), ECU part number is 37820-P2N-L31. I do not live in CA anymore so CA compliance should not be an issue (I moved to Europe several years ago).

I can source a Dorman manifold, federal compliant, for a good price. The question is will it work with my ECU? Would the secondary 02 sensor, reading a somewhat different 02 level, throw a CEL?

Cheers.
