ok my friend has a 93 FSB, and just put long tube headers on, then high flow cats, and glasspacks, and exited them before the rear wheels in the same set up 4WRB has in this picture. now when he starts it up it runs really rich, the cats turn cherry red, and he gets 2 ft flames popping out the tips, and it barely wants to run, hes gotta floor it to clear out all the extra gas or it just chokes itself. he put the o2 sensor before the cat on the pass. side. we all thought the problem was that it was just reading that its really lean because it was only on the pass side pipe. so he cut up some pipe and made an H pipe and ran the sensor right in the middle. didn;t cure the problem at all, it still flames out and turns the cats red, and dosn't want to run. and body got any ideas for what its runnin like sh*t?
