I can confirm this. I was one of the first people to get and install the redesigned pipe and I have never had another CEL come back after the installation.
I was told that the issue that in the original pipe, there were some "spacers" engineered into the pipe. Turns out that the HJS Catalyst does such a good job of scrubbing emissions that the spacer actually causes the code -- i.e. a delayed response from the downstream 02 sensor. The redesign eliminated the spacer and put it back in a more stock configuration, which eliminated the P013F code.
