I'd like everyone who wants to give their opinion to comment on the best exhaust, intake, and i've narrowed it to 2 H&S or Spartan. I do a ton of towing btw.

Don't know about exhaust or intake.. But if i were you Id go with H&S... customer service excels IMO..

i've been reading all the old threads for the last couple of days trying to decide what would work best for what I use my truck for. I also dont want my truck too loud, but i do want to delete all emission stuff, and go turbo back with 5''.

Can much be gained from tuning without deleting the dpf etc.? I would like to do something that will improve fuel mileage when I get mine but with the warranty don't want to mess with reinstalling the exhaust components for service.

So you don't want it "too loud" but you want to delete all of the emissions stuff and install a 5" exhaust? Hehe. Ok. Let me know how that works out. It's gonna be a lot louder than you are suspecting.

last truck was a straight pipe cummins. So anything with a muffler will be quiet in my opinion. I'm just not looking for an exhaust that makes it sound like a funny car

I strongly suggest H&S for the tuner and AFE for the intake and exhaust. Flo-Pro also makes nice exhaust kits.
