Take a look at my second picture in Post no. 20 of this thread.
You can see that these manifolds do not contain an O2 bung, but there is one at the front of the Circuit Werks resonators.
You need to fab up a pair of cable extensions for the FRONT O2 sensor so that it can reach the shown CW bung. A 'Search' of this forum will bring forth discussions about how to make these extensions.
Finally, you need to do a ROW tune which ignores the presence of the REAR O2 sensor since this system does not require the use of these second sensors. Thus, no dashboard warning lights.
