Don't give up on aftermarket. Lots of good exhaust shops can install a better converter than what the factory supplied. I didn't say that the part is cheap, but it's probably a lot cheaper than a Honda part and would work fine. I speak from experience, 30+ years as a mechanic and 19 years with a Calif. smog license. One thing, if you need a converter, please check or simply replace your oxygen sensor as a weak O2 sensor can ruin a converter given some time and that's often what causes the failure.. the other thing that kills converters is oil consumption or a coolant leak into the exhaust stream, Honda is not invulnerable to that.
