i have a 4-1 jdm style header that im putting on a obd0 b16a thats in my 91 crx si. the question i have is will it cause any problems moving my o2 sensors to a differant spot. like further down on the header.

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.
