dpf /exhaust removal ,no tunes ?

I have a truck that i have been working on for a few months (had to change motor)
I have done CAC , intake elbow , and egr delete with block offs .
I got the truck running just yesterday , and did not have time to get my spartan relicensed for today.
my question is , i want to go ahead and take the dpf out completely, and put in a new pipe .
If i can get the sensors out of the stock exhaust and installed , WIll it be ok driving it for a few days with out being tuned. ? Maybe sounds like a dumb question , but i am ready to drive and dont want to take any chances .
thanks in advance !

you need a tune with EGR delete and DPF delete, the truck wont run right after you take that stuff off in stock mode, it will go into regen and then stay in regen until you tune it.

It will basically just regen the whole time with out the DPF or Cat in place with out tuning regardless if the sensors are there or not. The sensors will pick up that something is wrong and try to go into regen and it won't come out until either tuning is applied or the DPF/CAT are replaced. You will be filling your crank case with fuel too so it will wash your bearings out not to mention run like crap and get horrible mileage. I would not drive it like this, you would risk ruining the motor and there not cheap by any means. Best advice I can give you is to either park it, re-install the DPF/CAT or get some tuning to allow you to run it deleted.

Thank you all for the advice !
I have not removed the exhaust as of yet , so is it safe to drive with it still on truck?
I have deleted the egr stuff , already though .

You will need offroad tuning for the EGR delete, it will limp the truck without it. I tried running mine this way when I first did my egr delete and the truck just had no power and could hardly get out of its own way.
