Dpf delete

I am buying the h&s mini maxx tuner I have that part figured out. Where I am un sure about is the delete pipe part and exactly what to go with. Should I get the cat/dpf delete or just the dpf delete pipe kit? Whats the difference? I also have seen recomendations for A 5" down pipe is that the best route to take? I am not trying to break the bank and the price range varies significantly. So exactly what do I need? I just need advice I want to do it right the first time. 2008 f250 6.4 powerstroke thank you.....

If all you want to do is get rid of the dpf, I would get the cat/dpf delete pipe. The cat and dpf are bolted together and much easier to take of and put back on as 1 piece. No need to keep the cat and only do the dpf because the cat is restrictive also.
If you want a full system, they delete the cat and dpf and you can get them with or without a muffler. It doesn't matter if you get 4 or 5 inch. Difference will be a little sound and price.
That being said, I just put a Flo-Pro 4" from the downpipe back on my truck with a muffler and its just fine for me.
The delete pipe only would be about your cheapest route and get the most restrictive parts of your stock exhaust freed up. I just had to get rid of those goofy tips on the stock exhaust also.

He pretty much covered it.

At the very least I would recommend doing a DPF/CAT Delete Pipe. If you are on a budget, that is all I would suggest doing. Let us know if we can help with anything. Thanks

Thats all I did. And if you decide on changing the tailpipe later, you can just get a filter back exhaust.

Couple questions, and forgive me, because I am new...
Can you get rid of the regen without a tuner? If I get rid of the regen and the DPF, would I have to increase my exhaust size to see any improvement in power/gas mileage.....my only true desire is to get better gas mileage...I really don't care about the power gains..if I increase my exhaust size, will that affect the spare tire storage?

Thanks.

You have to add some sort of electronic device(tuner) with modified exhaust to stop the regen process.

Getting an tuner like H&S xrt-pro with a cat/dpf delete pipe should be enough for what your talking about.

You will need some sort of tuner or device to shut regen off. Another thing you have to keep in mind is that the more power you add, the better fuel mileage you will get out of your truck as long as you drive it easy.

The DPF/Cat delete pipes will be much easier to install and more beneficial than just a DPF delete pipe alone. We have a package with that kit and the Mini Maxx on our site. Feel free to give us a call with any questions.

So they make a piece that replaces the cat converter and the DPF? I assume that does include the muffler....do they make a piece that goes from the cat converter to the end of the exhaust?

What are the benefits of replacing the exhaust from the cat converter all the way back? I guess the stock exhaust is 3"? I really don't want to affect the spare tire storage, so is that going to be an issue with replacing the entire exhaust?

If you do replace the cat and the DPF, do you still need a tuner...I understand you will need something to delete the regen...not even sure what the regen is (sorry guys)...I know it has something to burning off excess fuel for emissions (correct me if I am wrong)....what are the caveats to replacing the exhaust without deleting the regen...will it still try to regen and what will that do to the truck?

Thanks in advance, all.
