mikebontoft for what it's worth........I couldn't drill through the damn fouler, and when I got close I'd heated the thing up so much that all of the metal that came off of it got stuck on the threads and stayed there XP.

Anyone know if the long/deep foulers would fit our 02 sensors?

btw for what it's worth....... I've now been running for two days with an open header, first 02 wrapped around a hose in the engine compartment (the first 02 bung faces DIRECTLY toward an alternator stud. DAMN IT.) and the second 02 is just screwed in to the last hole on the header. no cat either. BOY is it loud but you know what? NO CEL! wtf. lol.

Correct!

I doubt I can fit 3 sensors in the collector proper. From photo's, it would appear that mounting a sensor (any) in the top/vertical location is constrained by the firewall/tunnel. Is there any reason anyone can think of that would prohibit placing a bung/sensor in the flex pipe itself?

Excellent. So I will need to measure the current length and add 1".
Thanks!

I would add 1 additional bung in the collector for an A/F meter. Could you expand your thought plz. Also, could you tell me about how long the 3rd o2 sensor with 2 anti-foulers is approx? I need to measure and mark locations.
Thanks!

If so, you need to add two more bungs in the header, one for the #2 o2 sensor (put a non-fouler on this) and then one for your wideband sensor. Then, way downstream after the catalytic converter, put a bung for that final #3 o2 sensor. I don't have the lengths, but two anti-foulers stacked on top of each other is about 1 inch long. You'll then need to add the length of the sensor.
