My first diesel!
This question was asked over at the other "Place" with no real explanation.
I finally got my 4-inch exhaust installed a few weeks ago. I have been able to take a couple of lengthy trips since then.
Why would my highway/cruise control fuel mileage be down with a more free flowing exhaust? (approx. 1-2 mpg's, measured with my Scanguage)
