Which exhaust?

[Crush80]

I am completely new to diesels. I recently bought a 2008 F250, 6.4. I am trying to figure out where to start as far as upgrades. I really am just trying to improve the mileage, right now I am not even getting 12.

Do you still have warrenty on your truck?

You will want a Tuner either spartan or H&S, CAI id go with AFE but there are others, for exhaust id do 5" straight pipe diamond eye is prolly the cheapest. Get with PTP Performance truck products they have really good prices and they are great people to work with

Like stated, you will need a tuner to run any kind of exhaust that deletes the DPF.

I recommend the Spartan Phalanx, AFE or S&B intake, and 4" AFE or 5" Flo-Pro exhaust. Let me know if you have any questions!
