Hey Chase, I've got a related question here.
I have a set of ARH headers with cats and I've started to get O2 sensor codes late last year. I've tried programming to eliminate the check engine light (by changing the O2 sensor threshold limit), but to no avail. This leads me to believe the cats are going.
So, I'm now looking for a new set of cats. Do you have anything available that will fit the ARH headers? I'm looking for something that's much better than the typical cats supplied by the header manufacturers.
