$5 o2 cheater/non fouler how-to
Available at your local automotive store. Spark Plug Non Fouler PN 42009 ($4.99)
You now need to drill out 1 of the non foulers using a 1/2" drill bit. When finished this is what it will look like.
Side by Side comparision of the orignal and now modified non foulers
o2 Sensor inserted in the modified non fouler
Second, unmodified non fouler now installed on modified non fouler
Original non fouler->Modified non fouler->o2 sensor
Fully installed
The idea behind it is when you remove the cat the 2nd o2 sensor is going to have too much crap reaching the sensor that isnt filtered out, which will make it think the cat has gone bad. What this does is it moves the o2 sensor further away so a limited amount of exhaust gets to the o2 sensor, it is a VERY little ammount that actually gets to the sensor but as long as it is considerably less than the primary o2 sensor then it wont cause a CEL.
from (http://www.k-series.com/forum/showthread.php?t=8833) pics rehosted by me incase the thread/pics disappear.
saw a few threads asking how to do it so i found it done w/ pics and decided to pass along the info

That is my write up I did a handful on years ago that I hosted on ephatch.com k-series.com i-vtec.net crsx.com and a handful of other Honda boards
I find it amazing how many forums my images/writeup has ended up on without any attempt to contact me before posting them.

I followed these step exactly (well, based on some common sense and a 1/2 bit and a vice) and the conclution is...
I have now installed this quick fix and it worked! I went to get the codes pulled to erase them and I had 5, mosly from vacuum rerouting and emission. All gone and it didn't come back when I gave the ole lead foot. We shall see but this looks very promising...
