Moses, I have an '87 Wrangler YJ that I'm looking to refurbish. I would like to replace the Carter BBD carbureted system. I have two questions: I have seen your articles on the Mopar MPI Conversion Kit and the MSD Atomic EFI kit. I'm leaning towards the Mopar kit but would like to see if you can provide a compare/contrast. My YJ will be much more of a Daily Driver with modest off road use. I would like to do a Cat Forward replacement at the same time that I upgrade to a new fuel system (I recently did a Muffler Back replacement). Do you suggest upgrading to a header application for performance improvement? If so, is there a header that requires no/minimum customization (i.e. can share bolt pattern with intake manifold and will follow the factory exhaust path configuration)? If you are suggesting a header upgrade, how choosy should I be with the cat selection? Many thanks.
