Tuner/DPF questions

[rodo]

Going Spartan and I have a few questions before I do.

1. I am really concerned about the warranty (I am going to purchase the 200k extended warranty before I Spartanize). Do you carry your original DPF and all tools to put it back on in your tool box, etc. on long trips? Worst case senerio, you are 700 miles from home and have a warranty issue.

2. Which is best...Cat on/off? Does it make for easier installation with a DPF/Cat delete over a DPF delete? More power? Other questions on this subject would be; Do you have to tune it different? (And the really touchy question...) Do you think it makes you more likely to get the infamous $10,000 ticket for missing equipment?

3. How many people have gutted a DPF to make it look stock once you tune? I know of one person on the forum...Do you see any issues with this?

Thanks in advance for any replies!

If you delete the dpf and doc it is one pretty big piece to carry around. It is easier to delete them both at the same time though as the dp has only 2 bolts as the dpf where it connects to the doc has 8 bolts. Not to mention the gasket that will probably need to be replaced if you take it apart that way.

If I was worried about fines, I wouldn't have even deleted the federally mandated dpf let alone the doc. (I did both)

A few people have gutted the dpf with good results from the sound of it.

If I have warranty issues far from home, I'm gonna be on this forum in the 911 section looking to borrow a dpf/doc LOL.

DPF/DOC delete is much easier to change and if someone is looking to see if you"re violating the law it won't make any difference whether you have one or both of them missing. If they're lookin for it, They'll know.
I don't carry my stuff with me, so I guess I'll keep my fingers crossed. If I'm close enough I'll have it towed home first. We all hope it never happens. Not much else you can do unless you wannna carry all of that crap around in the bed.
I've heard of a few people that have gutted DPF's, but I wouldn't gut your only one. They cost over a grand and you'll have to put a good one on if you need to take it into the shop for work any way. A full 4 or 5 in staight system will cost you less than half of that.

turbo back is everything from the turbo back, yes that includs the dpf/doc deleate. from what i have herd the downpipe is a PITA to remove without pullin the cab. when i tune my truck i will just be doing the dp back exaust

1. Yes, some people do take their stuff with them on long road trips. It is probably a smart thing to do for sure.

2. DPF/DOC is the easiest and best way to go. If the DOC is still in place on the exhaust and the DPF is off, there is a chance that the DOC could get clogged down the road. Either way, if the DPF is off the truck or they are both off the truck, you can still get the $10,000 fine. Its part of the game with these 6.4's. We just simply can't remove them under the law. If you choose to do so, then you risking getting caught.

3. As for gutting out the DPF, I wouldn't do it unless you have a friendly dealer that doesn't mind the modifications to the truck. I also would't do it if you don't have another DPF available to you if your dealer isn't friendly and you have to take it in for warranty work. When you go in for warranty work, the truck cannot be tuned, therefore the truck has to be in stock form, which means the DPF needs to be able to function like its supposed to.

jeff. So from what you are saying is it easier to do a dpf/doc pipe then get the exhaust from the dpf back>? I dont want to have to have a pain taking the cab off to install a downpipe . And I would like it to be easy to put the truck back to stock to take to the dealer.

It is easier to do a downpipe back exhaust. A DPF back exhaust doesn't do anything for the truck because it doesn't delete the DPF. It just improves the look.

AFE doesn't make a turbo back exhaust...atleast not that I know of. Their kit is a downpipe back exhaust that bolts up to the factory downpipe. Doing a downpipe back exhaust allows you to leave your stock exhaust intact, and it also means you don't have to use the factory tail section. You can just take the entire stock exhaust off, put it in the garage, and if you ever needed to put it back on its all there for you. I think it is a bigger pain doing a DPF/DOC delete because of the fact that the stock exhaust and the delete pipe will settle together after miles and miles of driving, and that makes them extremely hard to take apart IMO.

If I were to gut out a cat/dpf, it would be other than the one I have on my truck right now. Roughly, how long is the cat and dpf when you delete them? Will it fit in a toolbox in your bed?

[benjamin24]

Nope, it won't fit. When you get the chance go look under your truck right under the front passenger door and you should see the 2 bolts at the dp flange. Then go look at the exhaust right before the rear axle and the band around the exhaust there is what you will end up with doing the dpf/doc together.
