As the post says what exactly do o2 simms do? Are there any draw backs to using them? I ask because I was going to put them in the rear o2 sensors even though i still have cats because they are much cheaper than the 02 sensors?

There are 4 O2 sensors on our cars. The rear ones monitor the emissions output of the cats.

The Sims replace the rear O2's alowing you to run without cats.

If I keep the cats will they work still?

Does this mean that if you run gutted cats on long tube headers that you could still pass a computer emmissions check because you won't throw any codes?

That's true, you'll pass the computer emissions test, just hope the shop doesn't use a sniffer as well! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />
