Thread: Best cat to use with Speed Daddy headers?

Also heres a look at my o2 sensor voltages http://imgur.com/RnQnNer. They fluctuated as I drove, within .05 or so. As far as I know they look fine, but figured I'd present that information. Also here a some vehicle test results http://imgur.com/CqoyXhn. The code TID: $05 CID:$0a was not working properly, infact it was the only code that wasnt working properly. Its the rich to lean sensor switch and it hasnt calculated anything at all. Any ideas on what might be the cause? I'm thinking this is maybe one of the reasons why o2 wont show its ready yet. But I havent got a clue. If theres any more information needed I can try to provide more.
