Installing DPF/Cat delete pipes

I just want to make so I know what I am doing before jumping into this.

The cat is forward of the dpf right? They are both joined by a 7 bolt flange right? The cat is located pretty might right next to the lower control arm?

How the hell do you get the rubber deal off the exhaust hanger to drop the pipe - any special tricks? Are the delete pipes supported by anything once installed? I am pretty sure I know what is what underneath the truck but I just want to make sure.

Also, I know 1 sensor is not coming out but instead of buying a new sensor I thought of having all sensor bungs welded and just getting a custom tune - any exhaust shop should be able to do this pretty cheap right?

I think that is all I have for now.

Yes, that is the cat and the DPF is right behind it.

You dont need to remove the rubber adapter, you slide the exhaust hanger out of it which is attached to the exhaust pipe. It is MUCH easier if you spray the hanger with WD40 or other lube.

Im not sure what you are asking for the last question. You need DPF delete tuning if you plan on pulling the cat/DPF. If it is anything other than H&S, you will need the sensors back in the delete pipe(s). If you are having troubles with a sensor, put some heat to it. If that doesnt work, you will need to replace a Pyro sensor and/or buy a new pressure sensor adapter depending on which one is giving you trouble.

The sensor in the DPF I know that one is not coming out - I have tried it and I also know that it cost about 45 bucks - I was hoping to just take the pipes in to a shop have them weld a plug in the sensor bungs and then get a tune written that overrides the need for them. I thought Mike at KEM said he could do that in a previous conv. I had with him.
