Go Catless with the Gott's o2 sensor mod
I couldnt seem to find any threads about this mod, so I'm making one myself.
What does this mod do? this mod tricks your O2 sensors into thinking that your catalytic converters are still there so you do not throw a code when you cut them off.
How does it work? the spark plug non-foulers restrict the flow of gasses getting to the sensor therefore making it think the cats are still there filtering
Supplies needed-
now get under the truck and spray the living crap(for lack of a better phrase) out of the o2 sensors with your penetrating spray
while the PB is doing it's job go get your spark plug non foulers
and drill a 1/2" hole in the end of two of them. Careful not to booger your threads. This hole allows the top one to screw over the tip of the sensor shown here
After you have your holes drilled go inplug the sensors, use the little screw driver to pop the prong on the plug and relese it.
Unscrew the sensors from the pipe and take them out.
put the drilled out fouler onto the sensor first, tighten it down, then put a non drilled one over it and tightnem it down as well. it will look like this before you put it back in
Now screw it back into the pipe, tighten it up, then plug it back in
All thats left to do after that is hooking the battery back up.
Before I did this my CEL was on, when I started it up after this it promptly went off. As usual, if You have any questions I am happy to help

This does nothing to the actual emissions content of the exhaust gasses so it may or may not pass the sniff test. Depends on how dirty the exhaust really is.

Most inspection stations are really strict in NJ. A bunch of my friends have had their cats removed and they get failed because of emissions, but i do have some friends that have passed.
