Help Me pass Smog (running 2 rich)

Too rich equals less power. What is your A/F ratio? You need to lean your car up with a custom tune or a device such as a Preditor or Super Chips hand held tunner on a dyno. An exhaust system won't make you run any richer but after adding performance components you do need to tune your car. You could pick up 5 to 10rwhp if your running too rich which kind of negates the reason you put on performance parts.....Your A/F should be around 12.5 to 13 IMO.

This thread has nothing to do with making more power. He needs to pass emissions, not go spend another 300 for power. YES exhaust will make your car run more rich. It has been proven time and time again.

and actually NO, his a/f ration should not be in the 12s on a N/A stock motor. It would make more power in the 13s. With running all motor, you can get away with running a tad more lean. With that being said, all motors are different and like different settings/adjustments. My car like 12.8 at WOT even though Im all motor which is a little strange.
