Dealing with Headers, Cats, O2 sensors, and Emissions
I've searched through here but have found a whole lot of dead ends and threads that lead to unproven theories.
Can somebody give me info on the possibility of running headers, aftermarket cats, and still meeting emissions standards. I'm considering throwing headers on the green machine but want to do so in a fashion that still give me the ability to pass emissions legally.
I've heard about O2 sensors but it seems like that won't work. So what about the possibility of running atermarket headers, magnaflow universal cats, and a custom tune... or is that another dead end?
