Ask and you shall receive! Using two non-foulers.

looks like an o2 sensor plugged into the exhaust. The spark plug fowler screws onto the 02 sensor and encloses the sensor so the only exhaust it's getting is through a small hole in the bottom of the fowler. Next time you are in an auto parts store go find a spark plug fowler and it will make sense. I don't know if this link will open but here is what it looks like installed. Let me know if it doesn't open and I post it in cardomain: http://www.dodgetalk.com/forums/attachm ... tid=189597

I stacked two of them behind my high flow cat when I installed my mpx long tube and it works great, 0140 code went away right after I extended the wiring on my 2nd o2 and screwed it into place. It works.

do i drill out both non fouler?? how many miles did u put on it? with out a code coming back on?

nope, you don't have to drill out both. Just the one that holds the o2 sensor. I've got about 500 miles on it so far. I only had a code when it was un-installed and as soon as I got it back in the code was gone. I used one of the fowlers as the o2 bung that was welded into the exhaust pipe then screwed the fowler that i drilled out holding the o2 sensor into it.

This mod DOES work. I have been using it for like 30,000km without a CEL. You just need to make sure you don't drill out both non-foulers. If two non-fouler's won't work, use three. They are a hell of a lot cheaper then a cat, or o2 sensor, so you've got not much to lose, other then that pesky CEL.

Quite the bumpski
But just wanted to say that this mod DOES work. Threw mine in a couple days ago and no code. Even passed emissions with it

Will the neon pass a sniffer test with no cat?

I'm going to say no. However, I suppose there is a slim chance you might squeak by....depending on the stringency of the testing.

well i was doin some work on the engine and had the exhaust off so i hollowed out the exhaust and put on the 2 defoulers and i now need a new 02 sensor because the clearance was too close and it cut the wires on the sensor so depending on your cat you might need to clearance the body to make this fit or get the one from MP that does a right angle ill let yall know if i have the code after i get a new sensor
