At the request of several forum members I am putting together a grab bag of parts for a DIY DPF delete. I have the flanges already made up, and I am just looking for some more info out of you that have made your own. What the kit will be initially is a flange and some bungs for you to weld up your own pipe as you like. In the future I may offer my own finish welded pipe and plug and play resistors.
What sensors stay mounted in the tube and what thread size are they?
What ones get fooled with the resistors and what values work?
I know these are all in other places scattered about other threads, but I am trying to get the info in one place for all to read. Please try to keep "wow cool dude" posts to a minimum if possible.

Oh....please try out our search function link listed above, it actually works unlike other forums.
Pictures of what? He has nothing really to give you pictures of. I thought I heard that all the probes in the exhaust where the same thread size and that you can buy them to weld on..."O2 sensor bungs"...?

The 02 bungs are the standard size you can get at any muffler shop. The 3 EGT probes are M12 thread and you run 470 Ohm resistors on the probes or can run just 470 Ohm resistors with no probes in the exhaust. There are more resistor combos but that's what I am using. I am removing my probes with the 470 Ohm resistors, plugging the probe holes in the exhaust and just running 470 Ohm resistors in the 3 connectors here in couple weeks. Again that's just what I am running, others will be different.

agreed, he'll be the final vendor. Just looking for info here.

I really see no reason to put the probes in a delete pipe, I've run mine both ways and didn't notice a difference between straight resistors and resistors across the probes... not like it is going to look stock with a straight pipe in there anyway. 470Ω and 330Ω resistors both work for going straight across the 3 EGT connectors.
For wiring resistors across the probes most people use a 1kΩ on the front EGT sensor and 680Ω on the back two, 470Ωs across all 3 would probably work fine as well.
That said the only thing that I think needs to go back in the pipe is the 02 sensor, I believe it is a 18x1.5mm.
