Dpf delete pipe, 4" exhaust, and NO tuner?

Has anyone done this? With all of the current tuner/EPA confusion, I plan to just sit on the side lines until everything is squared away and H&S comes out with the best thing possible while still meeting all legal requirements.

The plan is the 4" flopro dpf delete pipe, which the lovely ups lady brought me today and the Dynomax 5" dpf back exhaust. Besides sound, should I expect any other changes? And in regards to the dpf and regenerating, will this never happen again since it's gone and my fuel mileage just stay the same, or should I expect to see the check engine light?

I'm still learning all I can about my new 6.7, so any help and advice is greatly appreciated!

I think you have to tune or the truck will go into limp mode. It would be bad if it tried to regen with no DPF. I wouldn't do it if I were you.

Yes, once you disconnect the sensors in the dpf pipe, it won't run for long before the ECM shuts it down.

Im not too updated on the newer technology, but i've read a few times where h&s discontinued a tuner and came out with another. Does that still turn the DPF off?

You need a dpf delete tuner, or race tuner. I'll pm you more info.

The truck won't run for more then about 30 seconds if you delete it and don't have a tuner. You MUST have one for it to run and be driveable. When you get a delete capable tuner installed you select "deleted" from the options and then it won't try to go into regen anymore, you will definitely notice a 2-3mpg increase in mpg easily and the best mpg comes on the highest power setting if you're running the H&S.
