[rjbrock495]

I was wondering if there are any mods that will bring up my mpgs with out breaking the bank. I figured a cold air intake and exhaust but that alone is going to set me back around a 1000. any pointers.... Im a new powerstroke guy that switched from the 5.9 cummins... thanks guys

Just to let you know, if you are paying $1k for exhaust and an intake, you are getting robbed. Exhaust at the most should cost $500 and you can do an intake for about $40. That is assuming you are doing the work.

Old diesel cats are not worth enough to worry about. New ones are worth a bunch of money

Just cut the kitty and the muffler out and weld in a piece of exhaust tubing in there place. Beating the insides out is way to much work

And a good chip is worth a couple mpg

Taking out the cats in all of my powerstrokes made ZERO MPG difference
