Default DPF And EGR Question

Hi, I'm new to the site. I currently have a 06 GMC LBZ, 4" turbo-back exhaust, afe Cold air intake, and edge with juice. I'm considering trading in for a 2008 chev LMM, but am afraid of all the emmissions garbage.

Is there a cat and dpf delete with the bungs so I can screw the sensors back in? If not what do you do with the sensors?

Can you turn off the regen with the LMM edge, if so will this stop it from going into regen mode?

Also how difficult is it to block the egr on the new LMM, I haven't looked under the hood of one yet.

Finally if I can delete the cat and dpf can I run LSD rather than ULSD, and can I use regular 15/40 oil rather than the "low ash" CJ-4 they recommend? Thanks any feedback would greatly be appreciated!

It depends what you want to do with the truck, I have about 21K on my truck with the all the emission stuff still on it and have no problems with regens or clogged DPF.

Not 100% sure about what you can do with the edge because I am not a fan of the edge. I know with some you can (Quad and PPE).

AS Tyler said you just take the sensors off when you remove the DPF.

I would not run LSD, in fact I cannot remember seeing a place that sells it anymore.
