i got a 99 accord, and i just got a jdm f20b motor to put in, on my motor (f23a4) the O2 sensor is on the exhaust manifold , and on the f20b the 02 sensor is down on the downpipe near the Cat. I look around and cant find any answer if the H22 usdm (97 up) aftermarket header will fit, or any answer on how i wound make it work and pass smog test. I need help Oh yeah and i found out that there is two type of header for the H22, swich one do i need the one for a SH or the stander one.

a header from 92-96 h22 will work

 

1) Should be for the H22 VTEC model, I believe the ports are the same on the F20B and the H22A

2) just extend the o2 wires and plug it up?

 

will the header bolt up to my stock exhaust system? i understand that a h22 and a f20b is the same thing, but if i'm not mistaking the h22 is a obd1 and the f20b is a obd2, will it still work, and on my f23a4 it has "2" 02 sensor, does the f20b have 1 or 2 02 sensor stock, how do i bypass the other sensor.
