Question Going to delete DPF maybe cat or both.

Ok just came back from my second camping trip and averaged about 8.2 mpg on a 2008 f350 cc dually 4x4 KR with 88k. I was hualing a 25 foot lite TT with some camping gear in the bed. The truck ran like a champ but damn MPG sucked. Well I want to get my mpgs up there. So if I'm going to delete do I just do the DPF or should I do the cat as well. Keep in mind I will have to reinstall everything once a year for emissions. Who has the best price for a dpf pipe and dpf program delete. I don't really care for a performance program. I just want to get my dpf as cheap as possible.

You can get away with just deleting the DPF unless your planning on making huge power and ripping your tires to shred, then I would suggest both. Removal of both will net you a little more then DPF alone, but you'll also end up with the infamous hair dryer sound as well.

If your expecting huge mileage numbers you will probably be sorely disappointed, especially while towing. Your best mileage will be unloaded and on the freeway. But no where near what others have posted sure to your gearing and wheel quantity unfortunately.

I'm not looking for more power. Maybe a little better mpg's. Wasn't sure if I should do both. Right now I'm looking at just doing the dpf pipe. Looking for a cheap tune to delete the dpf feature.

its easier to delete both. when you delete both, there are two bolts holding it to the down pipe, and one band clamp holding the dpf to the tailpipe. if you only deleted the dpf there are prolly 8-10 rusty bolts holding the two together thats a pain to get to the top ones with it still on the truck. if i were you i would look for a used h&s mini maxx or xrt PRO because it doesnt require sensors in the new exhaust. sct requires sensors in the exhaust and they tend to charge more for the bungs in the dpf delete pipe. spartan is more expensive plus if you buy new they charge a 100 dollar relicensing fee.

i went from averaging 9.8 mpg towing to about 12-13. not a huge improvement but enough to make me happy. i did an intake though too. i was hoping for 20 mpg like so many claimed but no luck. I once got 14.1 mpg but it must have been going down hill alot haha

I found a few dpf cat delete pipes with and without bungs. I was going to buy the one with the bungs. Just need to get a tuner to delete the dpf feature.

then find a used sct with some unlocks left, make sure its the off road version that is dpf delete capable. they are discontinued so somewhat hard to find. i think there are one or two for sale in the classified section. you will need to remove all the sensors from the dpf which is kinda a pain, and some buy extra ones so they dont have to swap them when going back to stock

the sensors going into the dpf. the h&s and spartan tuners dont need those sensors plugged in, but sct tuners need these sensors plugged in or the truck will idle at about 1200 rpms. they are just temp probes for the computer to know how its running, you wont lose any sensors that you will notice.
