I went with ARH, one sensor attaches at the lower portion of the headers and the other attaches on the tube portion with the cats, so 2 per side.

I heard the sensors were hard to remove, should I say anything to the place that installs mine or if all they do is this kinda work would they be familiar with it. I am going to a local guy who is highly reccomended and don't want to insult him by mentioning something that would be to him like tieing his shoes.

Not hard at all, they will know what to do. I'm no mechanic by any means or even a backyard one, thes took me and my friend on his dads lift just over 3 hours to install.

The top sensors on each side are the actual O2 sensor.
The lower 2 measure the condition of the Cats.
Even with the holes there you should have a tuner turn the bottom sensors off. Most times the engine will detect the fact that flow and AFR is different than with cats so the computer will think the cats are bad. it will then throw a code.

Once those sensors are turned off you can use that hole in the off-road pipe for a wide-band AFR gauge. With a wide-band you can almost tune yourself. At Least you will always know that you are running a safe tune if the afr looks good.

You use all 4 sensors. On both sides, one of the sensors attach before the cats and the other attaches after the cats. It's this way on the oem exhaust as well. If you are doing it yourself, you don't need to worry about getting them mixed up as the sensors are designed to only fit one way.
