I gutted my cat today, everything went fine no problems. After a couple hours of driving I got a check engine code (67).

Hybrid honda says that this code means

"malfunctioning or defective oxygen sensor heater"

What is wrong and how do I fix it?

 

talk to NekkedR he got a test pipe and still doesn't get a check engine with what he did....

 

Your secondary O2 sensor is telling the ECU that the cat isn't doing its job, (because none of the material is there anymore) thus throwing a code. There are a few solutions that people have come up with, such as wrapping the 02 sensor in foil before installing it in the cat or zip-tying the sensor next to the cat. You might want to check out the groupbuy center where there's a special on 02 simulators for testpipe (or gutted cat) users. Either way, the overall consensus is that a CEL caused by the secondary 02 sensor will not cause a loss in performance, so if you can deal with the CEL glaring at you then it shouldn't be a problem.
