I know most of you are running a Y pipe, so no one may know. For reference, I have a OBD1 355 LT1, forged, ported, big cam, in a 89 RX-7. I have dual exhaust at the moment and I am going to put in a crossover pipe. Since we really can't tune each side of the motor when in P.E., where should I put my wideband sensor? I am not sure if the crossover pipe will see enough exhaust to be accurate, I was thinking of putting it on the side of the motor that runs leaner.

Anyone have any other ideas on what I should do?

Thanks in advance, I hope I didnt post in the wrong area.

 

Put it in the crossover pipe, it will see as much pressure as the rest of the exhaust.

 

Has anyone done it? I am just not sure it will have the same amount of exhaust, but in theory it should.
