I'm looking at installing electric cutouts right before the cats on my 05 (Or maybe having a muffler shop, removing the cats completly as tehre are no emissions tests here) and I noticed when I was looking that the o2 sensors are right after the headers which makes it really hard to install cutouts and leave them reading properly. Also I beleive there are two more after the cats?

So where might I find fake o2 sensors and what risks do they run?

just out of curiosity where do you live

Get yourself a tuner and turn off the rear oxygen sensors.

According to his profile he lives in Edmonton, Canada. Guess they don't have emissions testing in Canada.

I didntknow a tuner could disable them. Will the xcal do the job?

So basically I could run a Y where the front sensors are with cutouts, tap a hole for the front sensors and disable the after cat sensors?

Does this risk running too lean (or rich) over time?

Cutouts before the cats would give you essentially open headers .... zero backpressure, very loud annoying exhaust and plenty of exhaust fumes in the car. Why would you want to do that?

Well when I had the muffler off I really liked the sound. I guess that could be due to the soundwaves being shaped cat back, perhaps a better choice would be right after the cats then?
