My mistake, missed where you said you went catless. I'm looking forward to updates on this. Nervous that my code will come back as I haven't had the headers in for long and want to be prepared if they do.

Hope it works. I had to use a flash to fix subsequent O2 cel. But it’s sorta hit or miss I’m told. I’ve got a set of minicats that I’ll sell. Didn’t fix my issue but works for some.
