o2 sims for the 3.4?

[camaro_zach]

I know there are o2 sims for the 3.8, but my buddy has 3.4 and he needs o2 sims. does anyone know if they are made for the 3.4 and if so where i can link him to buy them? Thanks.

Why does he need O2 sims for the 3.4? They only have O2 sensors in the exhaust manifolds so the PCM doesn't know any difference if you remove your cat or something.

As was mentioned above, you would not need O2 simms for a 3.4L V6. The only O2 sensor upgrades for our cars is converting to a 3-wire O2 sensor. This would give you a heated O2 sensor so that your O2 readings would be good at all times. With a high flow exhaust system, the single-wire O2 sensors sometimes don't heat up enough to give a good reading, but with the heated O2's, you will always give the computer the correct readings, resulting in better performance.
