Quick question. I know the DTLT's eliminate the Cats. Soo, what did those who are running this set up do with the rear sensors. Are they still pluged in? And if so do they need to be?

I need to run a wideband sensor, and Gadget's suggested area for mounting it is at the Y-pipe. Which is cool, because I did not want to weld into my new Headers.

What I was thinking of doing is capping both bungs in my URD Y-pipe with the Bung caps URD provides. Then, when ready to set up my A/F meter just screw the Bosch wideband plug on the passenger side bung. No extra welding needed.

Let me know if im smoking crack or something, but I am pretty sure that the rear O2 sensors are no longer neccessary to be mounted.

Thanks...

Sounds like you're on the right track. When you put the headers on you eliminate the first set of cats, so you'll need an O2 sim to trick the computer into thinking they are there. I used the empire sim because it's plug and play (http://www.empirepao.com/ #1303) but URD sells one that is quite a bit cheaper that requires cutting wires. I put bung plugs in the lower O2 sensors and maybe sometime in the future I'll get around to wideband tuning.

Are you still running stock y-pipe with two cats? because if you are, you cannot use the two rear bungs for wideband tuning. FYI

^That's what I figured. The DT's get rid of the first set of cats so putting the A/F after those in the lower bungs before the second set of cats would be fine because there's no cat before it. Good to know, but I doubt I'll get to it for a while, too many other mods higher up on the to-do list!

http://www.aprpower.com/ecu_tuning.html for what looks like a pretty solid description. trdparts4u.com has it for $200 less, but there might be better deals out there.
