Spartan or H&S?

[08TWIN6.4L]

I'm new to the Ford world.(Had 9 Dodges)I ran the XRT on my 6.7L and really liked it. I have been reading all about the Spartan and it seems really impressive. But I'm sure H&S will be on top of their game also. Also should I just get a cat/dpf 4" delete pipe or the whole thing? Please help me decide guys and thanks in advance. Later.

i'd go with spartan... H&S are at the top of thier game for cummins but too soon to tell for the 6.4. It depends on your preferences for the exhaust. it's a bit easier to just swap out a delete pipe instead of a full exhaust for warranty visits. i will get the full exhaust when my warranty runs out though. i'm sure mostly everyone else will give you the same answer

I would go with Spartan at this point. H&S has some proving to do, and there are currenty only tester units out. You could do a 4" or 5" downpipe back exhaust, or you could just do a DPF/DOC delete and keep the factory exhaust or put on an aftermarket DPF-back.

Im not up on 6.4's but everyone here will say Spartan.

Don't forget SCT... River City Diesel and Innovative both offer good custom tunes...

Spartan is definitely the way to go at this point, too early to tell on the H&S.

look at it this way......H&S tunes different trucks , as far as I know Spartan has almost totally built their buisiness around one...the 6.4. I have never been around either tuner all I am going by is what I read on here.

I cannot express how awsome Spartan is! its awsome stuff! And I would never buy any tuner that doesnt hack into the TCM and adjust to hold the power. stock 5R110W which is whats in your 6.4 (unless its a standard) can only hold 40-60 hp over stock safely without Trans tuning...anything other then that and you can kiss the life of your tranny good bye. Although I will say the 5R110w is gonna hold the power way better then the dodges tuned or untuned.

There will be TCM tuning with the H&S, that is why the moved their original release date back. All the feedback they got from this forum made them go back in and make changes. It will be a good product, it will just take some time.

Sct is a more inexpensive route but not as advanced as spartan tuning
