I have a 2007 4x4 4 door sport 4.0L. I'm looking into headers and dual exhaust. It's originally a California car but no longer resides there. I still have to pass an emission test every other year. My first question is will adding headers and dual exhaust affect an emission test? My next question is will I need to use a tuner to run headers and dual exhaust or will the stock computer handle the changes? My last question till I know the answers to these, will an H bar exhaust fit or is an X bar system the only option for my truck?
