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.

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

re: Straight pipe on diesel


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.

THIS

The skinny pedal directly controls how much fuel you burn.

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.
