Straight pipe on diesel

How much would that alone improve mpg's?

What model of diesel engine? Mine might have got 1 mpg better, maybe.

Depends on what engine and year. Other upgrades and programming may be necessary.

Didn't help mine much when I did it on my Dodge. Although I kept the cat and just took the muffler off.

2 or 3 mpg with straight pipe and H&S mini maxx on a 2008 dodge mega cab is what I got.

I basically went from 12 to 24.5 with a programmer, straight pipe, and intake
Damn gubment

Left mine stocked. Still getting 22.5 if I drive 45 or 85. 
Besides, I hate all the noise.

There is no magic that will give you miraculous gains...you will see a decent increase if you remove most all emissions...
But if you are only gonna straight pipe it, its not worth all that extra noise...
I didn't like the noise my MBRP Exhaust was making, so I put a Corsa diesel tuned muffler on it...you hardly hear it until you roll on the throttle...no drone either...
You want good mpgs? Put a block of wood under the go pedal...

If you have dpfe on it you will get no improvement if you remove the dpfe without a programmer chance of ruining the motor. If it runs on that urea crap keep it stock or you will be out of a truck. I do this shite for a living.

The skinny pedal directly controls how much fuel you burn.

What kind of truck are we talking about?

Use the skinny pedal less.
You'll get some good gains if you de-EPA the whole engine, but otherwise the best improvement you'll see is using less throttle.

But I'd de-EPA just to shaft the gubment.
