I can't mount it anywhere that the pipes are parallel to the ground because of condensation buildup. How can I mount the bung without having to remove the exhaust setup to do it? Can it be done after the headers, on the angled portion of pipe that connects to the catalytic converter?

I think for accuracy it would need to be infront of the cats
so since there are 3 stock O2 sensors (1 in each cat and one infront of a cat) so the other side that doesn't have a O2 sensor would be the place to go

There are 4 sensors, there are only 3 on the midpipe though....i was going to stick one where one of the rear 02s go, they are turned off since i have an o/r pipe so this will save me from putting a bung in

howarmat, would this affect your actual readout since it is so far away from the headers?

Ford_Dude

sorry my mistake
but for accuracy you'll want them close to the headers

howarmat

You want them as close as you can, the reading will be fairly accurate here as it would be the same as just before the cats on a normal system really...Dont know for sure since i havent ordered them yet...
