    like he said, no. Not so long as your header combines into pairs and then into a single. Which I doubt.

    OBD0 requires the O2 sensers to be paired on specificly 2 cylinders... It's 5 am here and which two cylinders escapes me. but that's how the STOCK ecu measures your exhaust gas as acurately as a single wire o2 senser can to achieve something close to a stoichiometric burn.

    So if they are in a line, series, farther down the pipe your car will alternate from lean to rich.
