I live in a country where the emmisions issues associated with a DPF delete arent a problem (legally speaking no one cares and wouldn't have an issue even if they did)
I found a couple of sources that discuss the matter but I have some questions, open question.
1) Anyone have a good trustworthy step by step to follow with regards to getting it done?
2) Let's assume I get a tuner and flash the ECU, once that's done is there any benefit or issue with leaving the exhaust assembly where it sits?( inc.. DPF, def manifold, and stock exhaust) ( other than sound and aesthetics that is)
3) once flashed, can the ECU be flashed back to factory?

Answers to these as well as comments are appreciated

Look on the forum there is a great walk through here.
pull the cans out from under there, they will plug up and you’ll be in worse shape than before
Yes you can go back to factory with the proper tune files.

You can leave the DEF tank, since that will be turned off with the tune. Everything else like the DPF and SCR need to come off. Here's a helpful step by step.
