Just put my cat back on. Question

[acelay]

I just put my cat back on, but had a question about a little knob( I guess that's what i'll call it). Please take a look at the picture below and tell me if anything connects to the little black knob (it's on the end of the cat where the cat connects to the dpf delete). I do not see anything that can connect to it, and I don't remember anything being connected there. I just want to make sure i'm not missing somthing thanks

I'm pretty sure that's the pressure sensor port. In the DOC/ DPF combo there are three temp sensors and one pressure sensor

Thanks, if so, is ok how it is? I remember seeing a video and i think there was something else attached to it. I'm not quite sure though

Yeah, the pressure sensor needs need to be attached to it otherwise exhaust gas will flow out of it.

This is interesting, does anyone have a pic of the pressure sensor because i do not see anything else under there I can attach to it or is this something I need to buy? I don't recall anything being there when I removed the exhaust.

One of the stubs that holds the DPF/DOC together has two nuts on it, that second nut is there to hold the pressure sensor that connects to that tube.

You are right, exhaust gas does come out of it. Dammit! There is nothing under there for me to attach to it tho?? At idle I can feel slight exhaust gas comming out of it, I had my girlfriend rev it and I did not feel any exhaust gas come out. Will it hurt my truck if I leave it how it is?

Assusming you're running a DPF delete tune (that sensor tells the computer when to order a DPF regen) you could plug it or leave it open, aint gonna hurt anything either way.

Ok cool, I do have the dpr delete tune on my h&s, so i'm going to just leave it how it is. Now if i were to put my dpf back on, I would need to hook that sensor up correct? I still do not see anything hanging or anything on the dpf that will attach to that litle black port
