Pro's to removal..no exhaust restriction or regeneration cycle = better performance
Con's to removal...reguires a tuner that will work with DPF delete and did i mention in some places its not legal?
DEF is a fluid injection that happens post DPF so technically you would still need to use it as it is operational but you could shut it down if you have a Tuner...but just remember it is also not the most legal.

MPG gains are not as impressive as the 6.4 ps but you will see some. Most delete for more power. The 6.7 dpf delete pipes also remove the scr cat ( which is what uses the DEF ), actually removing the tank is optional.

and maybe the +mpg is from removing the 800 lb gorilla under the truck they call a 'scr' muffler, etc 
While I tuned all previous ones and did all that, guess I'm happy with the way the 13 performs pulling our 5er, so I've left it alone.... and under warranty (so far!)
