Help please...O2 sensor question Options

[celi_gt_racer]

i'm workin on a 94' st celica atm, and it has 2 02 sensors, one in the header and one later in the flex pipe. We're putting on an aftermarket E-bay header and flex pipe, and the header itself has a spot for the first O2 sensor, but there is no hole for the secondary O2 sensor in the flex pipe. What am I to do? will the car run correctly w/ just the primary O2 sensor connected.....is there any kind of trick to get this set-up running correctly. any help would be apprechiated, we're tryin to get this car on the road at the moment

get a 2nd bung welded then google the "spark plug non-fouler trick" and you'll be all set with no check engine light when you connect and install that sensor.
